3 week of pregnancy from conception

What happens to the baby at 3 weeks

At the 3rd week of pregnancy, a lot of important changes take place with the baby. The main thing is that at this time most of the internal systems of the embryo are formed: the respiratory system, nervous, hematopoietic. At the 3rd week of pregnancy, the future internal organs of the baby, tissues, even the skeletal system are already being laid.

During this period, it is necessary to minimize the influence of harmful factors, – explains obstetrician-gynecologist Dina Absalyamova. – Avoid junk food and negative physical influences, for example, do not overcool, do not overwork, do not visit the X-ray room. Naturally, you need to forget about bad habits – smoking, alcohol. All this can negatively affect the development of the baby.

The 3rd week of pregnancy is very important, since during this period there is a serious threat of miscarriage. Therefore, it is better for a woman to give up outdoor activities and serious loads.

Fetal ultrasound

At the 3rd week of pregnancy, an ultrasound scan of the fetus is already indicative. The expectant mother will be able to consider the so-called fertilized egg, which is fixed in the uterus, or maybe there will be more than one. An ultrasound examination will immediately exclude an ectopic pregnancy, so it is recommended to do it at this time.

What ultrasound will not show is pathologies in the development of the fetus (it is too small) and the sex of the unborn child. But by the end of the 3rd week of pregnancy, with the help of a sensitive ultrasound machine, the mother can hear the baby’s little heart beating. If you wish, you can print a photo for memory.

Photo life

At the 3rd week of pregnancy, there are no noticeable changes in the woman’s body. In appearance, it will not be possible to suspect that she is in an interesting position.

Some especially attentive girls may notice that the tummy is slightly swollen and the jeans are not so easily fastened at the waist.

At this time, the cells of the fetus are actively dividing. The baby is still tiny, about 1,5-2 mm long and weighs about a gram. In the photo of the abdomen, 2 weeks of pregnancy and the 3rd child looks like a tiny dot, resembling a sesame seed in size.

What happens to mom at 3 weeks

A woman at 3 weeks pregnant, as a rule, already knows for sure that she is expecting a baby. The main sign of pregnancy during this period is the absence of menstruation. Provided that a woman has a regular cycle.

The fetus in the uterus is actively developing, and the mother’s body spends a lot of energy on this process. Hence the fatigue and weakness that some women complain about in the early stages.

It is observed at 3 weeks and a decrease in immunity. It happens due to the fact that the amount of hCG in the body of the expectant mother increases, preventing her body from rejecting the fetus. Sometimes because of this, the temperature rises slightly – up to 37,5 degrees.

Other serious changes occur with the mother at the 3rd week of pregnancy, in particular, the hormonal background of the woman changes. Under the influence of estrogen, the mammary glands increase, but because of it, headaches and dizziness can also occur.

Another hormone, progesterone, calms the muscles of the uterus, but at the same time relaxes other organs, such as the intestines. Due to the effects of progesterone, the expectant mother may experience heartburn and constipation.

What sensations can you experience in 3 week

It is at the 3rd week of pregnancy that most of the signs of an “interesting situation” make themselves felt. At this time, in many women, the breasts swell and become painful, and the nipples darken. At 3 weeks from conception, the first signs of toxicosis appear. Some dishes suddenly become damn attractive, while others literally turn back. The same goes for smells. Nausea can haunt the expectant mother not only in the morning, but throughout the day.

In addition, at the 3rd week of pregnancy, the following signs are observed.

• Fatigue and drowsiness, which are due to hormonal changes and the fact that the body spends energy resources on the development of the baby.
• Pain or cramps in the lower abdomen. They appear when the fetus attaches to the uterus, or when it stretches. If the pain is barely noticeable, then you should not worry. If discomfort is felt, consult a doctor, this may be a symptom of a frozen or ectopic pregnancy.
• Minor vaginal discharge. Usually these are brownish smears that a woman finds on her underwear. Sometimes such discharge is confused with the onset of menstruation, but they most often indicate that the embryo is safely fixed in the uterus.
• Bloating. It is caused by hormonal changes and changes in the diet of the expectant mother.
• Sensitivity and even soreness of the breasts.
• Mood swings influenced by hormones. I want to cry, then laugh, some girls admit.
• Frequent urination. This is due to the fact that a pregnant woman drinks more fluids, and the kidneys work more actively.

Monthly

Menstruation is the main indicator of pregnancy at 3 weeks from conception, or rather, not menstruation itself, but their absence. It is this week that they should start if you have a regular 28-day cycle. Didn’t start? Do you have strange sensations in the lower abdomen and chest pains? Then it’s time to buy a pregnancy test. At week 3, almost any test strip will show whether you are in position or not.

Be careful – at this time, some girls find smearing brownish discharge on linen. They do not necessarily indicate the beginning of menstruation, sometimes just the opposite – they are a sign of successful conception.

Stomach ache

Some women in the early stages of pregnancy experience discomfort in the lower abdomen. The pain is similar to what some people experience before menstruation. If the pain is moderate and does not cause you discomfort, you should not be afraid. Sometimes it is provoked by a visit to the gynecologist or sexual intercourse, or maybe it is associated with intestinal obstruction, which was caused by hormonal changes.

However, if the pain does not give you rest, it is better to report them to the gynecologist. Sometimes sharp, sharp spasms can be a signal of serious problems: cervical erosion, frozen or ectopic pregnancy.

In these cases, there is a high risk that the woman will need hospitalization.

“At the 3rd week, serious changes occur with the baby, during this period there are risks of abortion, so pain should be taken carefully,” explains gynecologist Dina Absalyamova. — Our life now consists of constant stress. Expectant mothers cannot lock themselves in an apartment and avoid society, and it is he who provokes experiences. Try to take care of yourself to the maximum during this period of bearing a baby, avoid worries and unpleasant emotions.

For a period of 3-4 weeks, an ectopic pregnancy also makes itself felt. At this time, the embryo, if it grows outside the uterus, begins to cause discomfort. It stretches the tissues, most often on the right or left lower abdomen, where the fallopian tubes are located. This is partly why pain during an ectopic pregnancy is often confused with appendicitis. With such pain, be sure to consult a gynecologist or go for an ultrasound. An ectopic pregnancy is dangerous and should be terminated as soon as possible.

Brown discharge

With mom at 3 weeks pregnant, a whole range of changes occur, including brownish discharge. If they are insignificant, this may indicate that the embryo has attached to the uterus. But in some cases, the discharge should alert the expectant mother.

– Brownish or bright red discharge, along with abdominal pain, may indicate a threat of termination of pregnancy, – clarifies obstetrician-gynecologist Dina Absalyamova. – You need to take especially seriously the bright scarlet discharge, they speak of fresh bleeding. It can happen when a fertilized egg, for example, is rejected from the uterine cavity. In such a situation, you need to call an ambulance and contact the gynecological hospital.
