Reasons for small gestational sac in early pregnancy

Everyone knows that during the pregnancy period, the gestational sac of women develops very slowly at the beginning, so many women may have a small gestational sac in the early stages of pregnancy. The slow development of the gestational sac will cause harm to the female body itself. For the fetus, it may also cause poor development of the baby or fetal malformation. So what is the reason for the small gestational sac in the early stages of pregnancy?

Some mothers experience a small gestational sac in the early stages of pregnancy and worry that the baby will be unhealthy due to abnormal development of the gestational sac. A small gestational sac may be due to the mother's physiological reasons or it may be due to infection during pregnancy that causes the gestational sac to develop poorly. What should I do if the gestational sac is too small in the early stages of pregnancy? Doctors say that mothers should be closely monitored if they have a small gestational sac, as an unhealthy gestational sac can easily lead to miscarriage.

What to do if the gestational sac is too small in early pregnancy

Pregnant mothers are always worried about the baby's development, especially in the early stages of pregnancy. There are many factors that affect the baby's development. So, what should I do if the gestational sac is small in the early stages of pregnancy? Can I continue to be pregnant if the gestational sac is small?

Reason 1 for small gestational sac: physiological reasons

Due to emotional tension and other reasons, pregnant women may have delayed menstruation, delayed ovulation, and late conception, resulting in a gestational sac that is smaller than the actual number of days of amenorrhea.

It is normal for the gestational sac to be small. As long as a dynamic examination after one week shows that the levels of chorionic gonadotropin and progesterone are gradually increasing, the gestational sac is continuing to grow, and the fetal bud and fetal heartbeat gradually appear, it means that the small gestational sac is due to physiological reasons such as delayed ovulation and late conception, and the pregnancy can continue.

Reason 2 for small gestational sac: pathological reasons

Due to poor development of sperm and eggs, infection of mycoplasma, chlamydia, rubella virus in pregnant women, or exposure to toxic and harmful substances during pregnancy, the gestational sac may be poorly developed and smaller than normal.

For pregnant women who experience the above situation, the gestational sac will continue to grow as time goes by during pregnancy, but no fetal bud or fetal heartbeat can be seen. In this case, the gestational sac is unhealthy and will eventually lead to miscarriage.

Can a pregnant woman continue to be pregnant if her gestational sac is small?

Can a pregnant woman continue to be pregnant if her gestational sac is small? Whether she can continue the pregnancy can only be determined after a week of dynamic observation.

A small gestational sac caused by physiological reasons is a normal situation. As long as a dynamic examination for one week shows that the levels of chorionic gonadotropin and progesterone are gradually increasing, the gestational sac continues to grow, and the fetal bud and fetal heart gradually appear, the pregnancy can continue.

The gestational sac is too small due to pathological reasons: In this case, the gestational sac is unhealthy and will eventually lead to miscarriage. It is best to go to a regular hospital for a curettage, then find out the cause and treat it symptomatically, and then get pregnant again after one year.

Regarding the question of whether you can continue to be pregnant if the gestational sac is too small, experts remind you: If there is no vaginal bleeding, sudden abdominal pain, etc., you only need to wait for a week and then go to the hospital for a reexamination.

What is the standard size of the gestational sac?

Pregnancy is a complex process. After the egg is fertilized, it enters the uterine cavity, and the embryo and its appendages grow and develop rapidly until they mature. There will be different changes in each week of pregnancy.

4 weeks: The fetus is only 0.2 cm. The amniotic cavity is formed just after the fertilized egg has implanted and its volume is very small. Ultrasound cannot show clear signs of pregnancy.

5 weeks: The fetus grows to 0.4 cm and enters the embryonic period. The amniotic cavity expands and primitive cardiovascular system appears, which may beat. B-ultrasound can show a small gestational sac, which occupies less than 1/4 of the uterine cavity, or a fetal bud can be seen.

6 weeks: The fetus grows to 0.85 cm, and the head, brain alveoli, facial organs, respiratory, digestive, and nervous organs are differentiated. The fetal sac is clearly visible on B-ultrasound, and the fetal bud and fetal heartbeat are seen.

7 weeks: The fetus grows to 1.33 cm. The embryo has the rudiments of a human being. The body segments are fully differentiated, the limbs are separated, and various systems are further developed. B-ultrasound clearly shows the embryo and fetal heartbeat, and the gestational sac occupies about 1/3 of the uterine cavity.

8 weeks: The fetus grows to 1.66 cm. The fetal shape is determined, and the head, body and limbs can be distinguished. The head is larger than the trunk. B-ultrasound shows that the gestational sac occupies about 1/2 of the uterine cavity, the fetal shape and fetal movement are clearly visible, and the yolk sac can be seen.

9 weeks: The fetus grows to 2.15 cm, the head is larger than the body, the various parts are clearer, the skull begins to calcify, and the placenta begins to develop. B-ultrasound shows that the gestational sac almost fills the uterine cavity, the fetal outline is clearer, and the placenta begins to appear.

10 weeks: The fetus grows to 2.83 cm, all fetal organs have been formed, and the rudiments of the placenta are formed. B-ultrasound shows that the gestational sac begins to disappear, a crescent-shaped placenta is visible, and the fetus is active in the amniotic fluid.

11 weeks: The fetus grows to 3.62 cm, the fetal organs develop further, and the placenta develops. B-ultrasound showed that the gestational sac had completely disappeared and the placenta was clearly visible.
