What happens at 3 weeks of pregnancy from conception

Changes in the mother's body at 3 weeks of pregnancy

After 3 weeks of pregnancy, a woman undergoes noticeable changes throughout her body. After a woman finds out about pregnancy, she blossoms outwardly, this affects the condition of her skin, her gaze becomes tender.

Some female representatives can be aggressive and irritated. The uterus and mammary glands swell, hormonal changes begin. Appetite changes; there may be a complete refusal of any food or, conversely, gluttony.

Feelings in the third week of pregnancy

Many people are interested in what happens to the fetus at 3 weeks of pregnancy and how does the woman feel? In fact, at this stage there are no fetal movements; the belly is not yet visible. Due to hormonal changes, the body begins to adapt to the new job.

Many experts note that it is at 3 weeks after fertilization that women miraculously begin to feel their pregnancy. If you haven’t taken a test before, haven’t had any tests and don’t know that you’re pregnant, since there were no signs, then it is after 20 days from the moment of conception that you may experience the birth of a new life.

Sensations in the third week of pregnancy are compared with symptoms similar to those in the second half of the menstrual cycle.

Due to the production of progesterone, the mammary glands become coarse and swell, the nipples become sensitive, and nagging pain in the lower abdomen may be observed .
Women suffering from PMS feel the third week of pregnancy more clearly; they are whiny and irritable.

Symptoms characteristic of this period

In fact, we can safely consider the 3rd week after conception to be the beginning of pregnancy. From this time on, the expectant mother begins to experience new sensations for her. This is due to the fact that from the moment of actual conception the stage of global “restructuring” of the body opens. New changes that have replaced the usual processes of life are accompanied by characteristic and other signs (swelling of the mammary glands, discharge that does not resemble menstruation, etc.). Although in most cases it is difficult to call such sensations obvious, they can indicate the current situation, which will be confirmed by ultrasound, and how the process of the birth of a new life proceeds at this stage. What exactly and why can happen to a woman’s body during this period, read on.

What happens to the embryo at 3 weeks of pregnancy?

Many people are interested in what happens to the size of the fertilized egg during pregnancy from conception 3 weeks in the photo? The embryo at 3 weeks of pregnancy is very small.

The embryo is in the morula stage - a dense, round lump of cells. The morula turns into a blastocyst. This means that a cavity with fetal fluid is formed inside the lump, in which the baby will develop.

By the end of the third week after conception, the fetus measures 0.1-0.2 mm. The formation and development of the main body systems begins, and the tiny heart will make its first beats. To get an idea of the size and position of the embryo, look at what a baby looks like at 3 weeks of pregnancy in the photo.

3rd week of pregnancy - ultrasound

Ultrasound of the fetus at 3 weeks of pregnancy

Not all expectant mothers do an ultrasound of the fetus at 3 weeks; at this point many still do not know about their situation. If you already know that you are pregnant, or you have suspicions, then go for an ultrasound.

What can be seen on an ultrasound at 3 weeks of pregnancy? From the moment of 3 weeks after conception, an ultrasound can examine a small embryo, its location and other nuances.

An ultrasound can assess the condition of the fetus, the size of the uterus, endometrium, and see where exactly the embryo has attached. The size of the uterus changes during the 3rd week of pregnancy.

An ultrasound determines the exact stage of pregnancy. At this time, ultrasound can be performed using an external sensor or a transvaginal one.

Before going for an ultrasound, look at a photo of the fetus at 3 weeks of pregnancy.

What you need to know about the third week of pregnancy

If during 3 weeks of pregnancy your stomach hurts like before your period, this does not always mean the possibility of a miscarriage. For some women, it is in the third week that such sensations accompany the course of pregnancy.

What is the norm for progesterone at 3 weeks of pregnancy? In the first three months, normal progesterone levels range from 9 to 468 nmol/l. In the third week of pregnancy, progesterone should not exceed 50 nmol/l.

If the delay is 3 weeks and the test is negative, is pregnancy possible? In fact, each body is individual, and it is quite possible that pregnancy will appear on tests a little later. There is also a possibility that you did the test incorrectly. If you think you are pregnant, then donate blood for the hCG hormone.

Lifestyle in the third week of pregnancy

After realizing that you are pregnant, evaluate your lifestyle. There is no need to radically change good habits, but changes are necessary. You should eliminate strength training in the gym, stop training, doing physical work, and getting nervous over trifles. If you smoke, then you should get rid of this habit, since nicotine negatively affects not only you and the people around you, but also the unborn child.

Nutrition at 3 weeks of pregnancy

The first 3 weeks of pregnancy are extremely important in terms of nutrition.

Include the following foods in your diet:

lean veal, beef, skinless chicken;
lean fish;
fresh vegetables, herbs, fruits, berries;
boiled eggs;
dairy and fermented milk products with minimal fat content;
nuts, raisins.

All these products are rich in vitamins and microelements; they help the unborn child build cells, develop properly, and support the expectant mother’s immunity. During this period, you should not eat for two. It is enough to increase your usual consumption by 300 calories.

Divide the food into at least 4-6 meals. Consume more juices, fruit drinks and natural compotes.

In the third week of pregnancy, it will be important to eat berries and fruits with yellow skin. For example - bananas, peaches, apples, apricots, melons, carrots, pumpkins, some varieties of tomatoes. Eat whole grain bread with hard cheese, use natural yogurt without artificial colors.

Third week of pregnancy - 13 symptoms

The third week of pregnancy is an exciting time for an expectant mother. At this stage, some already know about their situation, while others can only guess based on their own feelings.

From this article it will become clear what signs indicate pregnancy and how it affects your usual lifestyle.

Here the reader will find information about proper nutrition in the third week of pregnancy.

Signs of the birth of a new life and feelings of the expectant mother

The third week of pregnancy after conception corresponds to 6-7 obstetric weeks. This difference is due to the fact that in gynecology the period is counted from the first day of the last menstruation. And the embryonic (true) period from conception is the first day of menstruation plus another two weeks (but we will talk about the intricacies of calculation in another article).

During this period, significant hormonal and physical changes occur in a woman’s body. You can recognize an interesting situation by the following signs:

Delay of menstruation. This is the most important and surest sign of pregnancy.
Chest pain. Any touch to it causes pain. The mammary glands enlarge and the nipples become hard and rough.
Nagging pain in the abdomen, as during PMS.
After sexual intercourse, pain in the vagina may occur. This is a normal phenomenon and passes quickly.
Frequent urination and occasional constipation.
Changes in the nature of discharge. They can be pink, white or light yellow in color with a sour odor.
Increase in body temperature to 37.2 0 C without any signs of disease.
There is a slight rash on the face .

In addition to external signs of pregnancy , the following symptoms indicate an interesting situation in the third week:

Slight nausea in the morning or after meals. Possible vomiting.
Changes in taste preferences, loss of appetite. A once-favorite dish is disgusting. Or, on the contrary, an unloved product becomes the main component of the menu. Taste quirks may appear, the woman begins to experiment with food, combining a variety of products, which she has not done before.
Increased sense of smell and sensitivity to odors.
Sudden mood swings, irritability, short temper, tearfulness.
Constant fatigue, desire to sleep, despite proper rest.

The appearance of the expectant mother remains virtually unchanged, but she becomes more feminine and graceful. Normal weight loss or gain is within 300 g, and an increase in the waist by a couple of cm.

What happens to the embryo in the third week of pregnancy after conception?

The embryo is a set of 250 living cells. It is a round lump, similar to a blackberry or a semolina grain. It is no more than 0.2 mm in diameter and weighs about 3 micrograms.

Despite its tiny size, the embryo already has genetic material that it inherited from its parents. Sex formation is already beginning, however, visible sexual characteristics will become noticeable much later.

The neural tube is formed, the spinal cord and brain are formed. At this stage, the embryo forms 3 layers of cells from which organs and tissues will develop.

At this stage, the embryo is fixed in the uterine cavity. This process takes about 2 days. A pregnant woman may have slight bleeding, which may be faint brown or pink streaks. By the end of the 3rd week, the embryo should be firmly established in a favorable environment.

At the same time, the placenta is formed, thus establishing a close connection between mother and child. Through the placenta he will receive vital nutrients and oxygen. It will also protect the fetus from negative influences and prevent the penetration of harmful substances.

How to behave while expecting a baby

While pregnant, a woman is obliged to take care of her own health and the health of the baby.

Take vitamin complexes high in folic acid. Choose the appropriate drug according to your doctor’s recommendation.
Give up bad habits. Do not smoke or drink alcohol.
Avoid stressful situations and nervous tension. Strive to receive only positive emotions. The mental state is completely reflected in the baby.
Do not lift heavy objects and avoid significant physical activity. Better go swimming or yoga.
Take a walk in the fresh air every day. This way the body will be saturated with oxygen, and the risk of involuntary termination of pregnancy will be minimal.
Choose comfortable clothes made from natural fabrics. Wear flat shoes.
Do not give up sexual activity if it brings you pleasure and there is no threat of termination of pregnancy. During the first trimester, some women experience increased sexual desire, while others experience a noticeable decrease in libido. Avoid sex completely if there is a risk of miscarriage.

These simple rules will make you feel comfortable and safe in this state.

How to organize meals: necessary and healthy foods and forbidden foods

The diet in the third week of pregnancy should be complete and balanced. To reduce the load on your digestive system, eat small portions 5-6 times a day.

You can snack between meals. There is no need to “eat for two”; it is enough to increase your usual diet by about 300 calories.

Drink up to 1.5 liters of liquid per day. This volume includes not only clean water, but also other drinks. If there is no predisposition to edema, then you can drink up to 2 liters of liquid per day.

Among the permitted and necessary products:

lean, lean meat: beef, veal, turkey or chicken;
fatty fish;
cereals;
boiled eggs;
legumes, walnuts;
dairy and fermented milk products, hard cheese, natural yoghurts;
fresh vegetables and fruits, berries, raisins.

Meat contains a large amount of protein, and fish supplies the body with important acids. Vegetables and fruits are a storehouse of vitamins and microelements. The healthiest fruits are yellow fruits - peaches, apricots, bananas and melon.

Eggs, nuts and raisins are filled with microelements that contribute to the structure of body cells and the proper development of the fetus. In addition, you can eat coarse baked goods or whole grain bread. Steam food, eat baked or boiled food.

Introduce iodine-rich foods into your diet for proper development of the sex glands. Zinc is necessary for the growth of the fetus, calcium for the formation of teeth and bones, and protein will build the muscles and tissues of the embryo.

Fried, spicy and fatty foods are prohibited at this time. Don't eat white bread, sweet buns, sandwiches and fast food - they won't do any good and will only add extra pounds. Mushrooms are also hard food for the stomach.

Don't drink carbonated drinks. Gradually reduce the amount of coffee and tea, as caffeine negatively affects the nervous system of the fetus and impedes the supply of oxygen to it.

Conclusion

In these extraordinary times, it is important to take care of your health and make every effort to ensure that the embryo develops into a healthy and full-fledged child. Monitor your mental and physical state, rest. Eat right and rationally. Enjoy happy moments, and difficulties will soon be left behind.

What can go wrong at 3 weeks pregnant?

If you feel that something has gone wrong, then do not panic. Make an appointment with a doctor, go for an ultrasound. In fact, if the pregnancy proceeds without complications, then everything should be fine at this stage.

Many women are concerned about the question of what to do if their breasts stop hurting at 3 weeks of pregnancy? In most cases, the pain subsides closer to the 11th gestational week, when the process of enlargement of the lobules in the breast and dilation of the ducts comes to an end.

These are approximate figures and may not apply to every woman. It is quite possible that if your breasts stop hurting earlier than this, then this is just your peculiarity, but you need to consult a doctor.

Ectopic pregnancy at 3 weeks

A sign of an ectopic pregnancy at 3 weeks is the abnormal placement of the egg when it settles before reaching the uterus. Most often it is attached to the fallopian tube, but sometimes other placements are possible.

Diagnosing the ectopic location of the fetus is difficult, since the symptoms of pregnancy are equivalent to normal, normal.

However, ectopic pregnancy is already accompanied by bloody dark discharge in the early stages. When the next menstruation due to an ectopic pregnancy is three weeks old, discharge is possible, only less pronounced than usual. A nagging pain begins to radiate into the anus, and when the fallopian tube ruptures, the pain becomes almost unbearable and blood begins to be released - the woman needs to be hospitalized urgently.

If there is any suspicion of an ectopic pregnancy, the woman needs urgent help and consultation with a specialist.

Frozen pregnancy in the third week

Frozen pregnancy at 3 weeks - what is it and how to recognize it? A frozen pregnancy is a normal fertilization that has occurred, but for some reason the fetus has stopped developing.

Frozen pregnancy is characterized by discharge, as during menstruation; it can be scanty or abundant. The discharge may be red, brown, or of an unknown color.

If, at 3 weeks of pregnancy, the lower abdomen pulls, as during menstruation, this does not always mean any problems with the embryo, but such symptoms may indicate various disorders. If there is any suspicion, consultation and an in-person examination by a specialist is required.

A frozen pregnancy can occur for various reasons. The most common is genital tract infections.

Miscarriage at 3 weeks of pregnancy

Miscarriage at 3 weeks of pregnancy can happen for various reasons. Many women at this stage do not yet suspect the presence of pregnancy and mistake various vaginal discharge for menstruation, thrush or other problems.

A miscarriage is characterized by bleeding of any intensity and pain of a wave-like nature. Miscarriage discharge is mostly red and brown. Sometimes pieces of flesh come out with the discharge. In this case, the woman needs to get help immediately.

Miscarriage can occur for various reasons. The main ones are physical activity, stress, smoking, drinking alcohol, infections and more.

Discharge in the third week of pregnancy

During the 3-week period, various discharges may occur; they do not always indicate pathology, but require examination and consultation with a specialist. Brown discharge at 3 weeks of pregnancy may indicate detachment of the fertilized egg, ectopic pregnancy and the threat of miscarriage.

If during 3 weeks of pregnancy the discharge is bloody, this indicates the development of the placenta, and as it grows, capillaries rupture.

Blood in the third week of pregnancy is not always dangerous, but requires careful monitoring. This is how implantation bleeding can occur - a sign that the pregnancy has begun successfully and the egg has implanted in the uterus.

It happens that at the 3rd week of pregnancy there is a tightening in the lower abdomen. There is no need to panic ahead of time, this may indicate hormonal changes, a cold or another PMS.

Nausea at 3 weeks pregnant

Can you feel sick in the third week of pregnancy? Yes, it can, since toxicosis begins from 2 to 8 weeks. Toxicosis during pregnancy at 3 weeks is noticeable in almost all women.

Nausea mainly occurs in the morning. Toxicosis can begin due to restructuring of the endocrine, nervous and hormonal systems. Review your diet.

Abdominal and lower back pain at 3 weeks of pregnancy

If your lower back hurts during the 3rd week of pregnancy, this may indicate PMS, a cold, or pregnancy. Colds in the 3rd week of pregnancy are not uncommon, as the immune system weakens and the pregnant woman is exposed to viruses and colds. During the season of acute respiratory infections and acute respiratory viral infections, drink more fruit drinks, vitamins, and warm yourself.

If you have a fever at 3 weeks of pregnancy, you should consult your doctor. Sometimes during pregnancy and PMS, the temperature may change. At low temperatures, tea with raspberries works well. It is not advisable to take antibiotics at this stage, or indeed throughout pregnancy, so take care of your health and dress for the weather.

Three weeks pregnant, stomach hurts

If this did not happen earlier, then it is at the beginning of the 3rd week that conception will occur.

If your egg has already been fertilized by a sperm at this point, then for about a week it moves through the fallopian tubes, continuously dividing and multiplying.

And now, at the 3rd week of pregnancy, it will attach to the wall of the uterus, and from now on we will talk about the fact that pregnancy has occurred and the fetus is developing in your womb.

The fetus at the 3rd week of pregnancy is so small that it’s hard to even imagine: only 2-3 mcg in weight and 0.15-0.2 mm in length. But by this moment it had grown disproportionately and increased in size compared to the egg.

After fertilization, it began to be called a zygote and began to rapidly divide, forming more and more new cells. The zygote resembles a mulberry, which constantly increases in size.

On days 7-12 of its journey through the fallopian tubes, the zygote reaches the uterus and begins to settle into a permanent place of residence. And after that it will be called a blastocyst.

The blastocyst is constantly in the process of development and growth. Very soon it becomes hollow inside and lengthens. Then an embryonic disk is formed in it, which by the end of 3 weeks will curl up into a cylinder with ends of different widths: a head will begin to form on one of them, and a tail on the other. Even though the embryo is still very small and primitive, the main organs and systems are already being formed.

At 3 weeks of pregnancy, the fetus is just trying to settle in your body, which still perceives the little one as a stranger. There is something like a struggle going on between them, and if a compromise is found, then very soon you will find out about the pregnancy.

Signs and symptoms at 3 weeks pregnant

In the meantime, you are just waiting for the onset of your next period, so you perceive the first signs and symptoms of pregnancy in the 3rd week as premenstrual syndrome: nausea, changes in appetite and taste preferences, odor intolerance, irritability, weakness, engorgement and tenderness of the mammary glands, frequent urination, nagging pain below stomach – the vast majority of us experience these symptoms every month. Signs of pregnancy at 1 week can be the same, so most often at such an early stage we do not even realize what is happening.

I have a stomachache

Among other things, at the 3rd week of pregnancy, a woman already has a stomach ache (although not at all necessary): the lower abdomen is stretching, as before menstruation - the blastocyst is preparing a place for itself to plant, as if scraping out cells from the uterine epithelium.

Not everyone feels pain, but if you have a stomach ache at 3 weeks of pregnancy, you can only suspect the real cause if you strive for it for a very long time and try to look for signs of pregnancy in any changes.

Otherwise, the woman is confident: menstruation is about to begin, although this time it seems a little earlier than usual.

Discharge

This idea will be prompted by discharge during the 3rd week of pregnancy, which is called implantation bleeding. The implantation of the egg into the uterus does not pass without a trace, and in addition to pain in the lower abdomen, it reveals itself as bloody spotting at the 3rd week of pregnancy. This phenomenon should not cause you any concern.

However, this often happens: a woman thinks that her period is starting prematurely. And only after this discharge disappears at the 3rd week of pregnancy, and menstruation does not occur, does she think about the possibility of fertilization.

The onset of menstruation and subsequent ovulation will be hampered by hormones - estrogen and progesterone - which begin to be actively produced by the ovaries from the 3rd week of pregnancy.

Discharge at the 3rd week of pregnancy is very scanty, sometimes in the form of a few drops or a smear, or even completely absent. They may be creamy, yellowish, pink or brown, disappearing and reappearing when the settler is more active. But after 2 days, the “daub” should stop - the implantation period lasts about 40 hours.

Breasts at 3 weeks of pregnancy

One of the earliest signs of pregnancy may be changes in the breasts, which is also observed at 3 weeks.

The mammary glands become rough, the nipples become hypersensitive and react very painfully to any irritation. Breast enlargement is also noted.

However, all these symptoms are also characteristic of premenstrual syndrome, so in isolation they cannot indicate pregnancy.

Sex

Another clue may be a change in libido at the 3rd week of pregnancy, in either direction: you may either experience an increased desire for intimacy with your husband, or, on the contrary, noticeably become colder in this regard.

Hormones, what can you do about it... But if your new pregnancy has awakened the woman in you, then enjoy it.

There can only be two contraindications to sex in the 3rd week of pregnancy: the threat of abortion and the woman’s reluctance.

Is it possible to drink alcohol in the third week of pregnancy?

Alcohol during the 3rd week of pregnancy is strictly contraindicated. As soon as you find out that you are pregnant, eliminate all bad habits. At this stage, all organs of the child begin to develop; no alcohol can be in the diet at this time. And even if a pregnant woman drinks a couple of sips or glasses of wine, there is a risk that this will cause subsequent changes in the child’s brain, the damage from which may not appear immediately.

Once in the blood, alcohol deforms the vascular system, liver, and brain. The mental abilities of a child whose mother drank alcohol will also lag behind those of his peers.

Emerging problems

One of the main and most dangerous problems is ectopic pregnancy . For a number of reasons, the fertilized egg can implant in the fallopian tube rather than in the uterus. In addition, the blastocyst can attach to the ovary or even enter the abdominal cavity. In all such situations, an ectopic pregnancy is diagnosed. Its outcome is obvious - the child cannot develop in such conditions. You have to get rid of an ectopic pregnancy, otherwise serious bleeding may occur, which poses a threat to the patient’s life.

Most often, ectopic pregnancy develops in women suffering from chronic inflammatory diseases and abnormalities of the uterus and appendages, as well as in patients who have undergone IVF (in vitro fertilization) procedures.

The second common problem at the end of the 3rd week of pregnancy is bleeding. Its appearance may be associated with implantation of the fertilized egg or some gynecological diseases. In any case, you should consult a gynecologist.

Is it possible to have sex at 3 weeks pregnant?

Is it possible to have sex at 3 weeks pregnant? The issue is controversial, since it depends on the emotional and physical mood of the woman. In general, having sex is not prohibited. If the test shows 2-3 weeks of pregnancy, and you are full of strength and sexual energy, then careful, calm sex will not interfere with normal development. The baby will not get injured, the main thing is that it is vaginal contact.

The embryo itself is surrounded on all sides by amniotic fluid, which in turn is protected by the muscles of the uterus. In addition, the cervix, where cervical mucus is located, protects the baby from the penetration of various microbes.

In what cases is sex in the third week of pregnancy contraindicated:

Risk of miscarriage. If the tone of the uterus in a pregnant woman is increased, then, regardless of the period, refrain from intimate relationships.
If this is not your first pregnancy, and previous ones ended in miscarriage, frozen pregnancy, or premature birth.
Placenta previa. In some cases, placental abruption may occur during sexual intercourse and bleeding may begin.
Genital tract infections. The embryo will not become infected, as it is reliably protected from external influences, but for the expectant mother, any bacteria are harmful. The most dangerous are chlamydia, syphilis, and hepatitis. These diseases weaken a woman’s body and harm the embryo.
Pathologies of the female genital organs - isthmic-cervical insufficiency or problems of the amniotic sac.

Don’t be shy and ask your gynecologist all the questions you have, including whether you can have sex in the third week of pregnancy.

What to remember

In the third week of pregnancy, alcohol and nicotine are contraindicated, since at this time all the baby’s organs are developing at the cellular level.
To know what an embryo looks like at this stage, look at the 3 week pregnancy photo.
Due to hormonal changes in the 3rd week after fertilization, a woman may experience toxicosis, spotting from the vagina and nagging pain in the lower abdomen. It is not necessary that all of these symptoms indicate pathology; in some cases this is a feature of the body.
