How long does it take to see the gestational sac during pregnancy? What should I pay attention to if the gestational sac is small?

Pregnancy is a very joyous event for a family. After discovering the pregnancy, you should have regular checkups and take folic acid and other medications to ensure the healthy development of the fetus. The fetus starts out small and grows slowly. The gestational sac is the original form of the placenta. By observing the gestational sac, you can roughly judge the condition of the fetus. So how long does it take to see the gestational sac during pregnancy?

How long does it take to see the gestational sac during pregnancy?

The gestational sac is usually visible around 40 days of pregnancy.

The gestational sac is the original form of the placenta. The main purpose of checking the gestational sac in early pregnancy is to determine one thing, that is, whether it is inside or outside the uterus. When seeing the gestational sac in the uterus under B-ultrasound, many pregnant women will breathe a sigh of relief, but in fact you can't relax yet.

Because even if you see the gestational sac, it is possible that it becomes an empty gestational sac and still cannot conceive a life due to sperm quality, environmental pollution, etc. Of course, this situation is rare after all, but it is also very worrying.

It is not until around 60 days that the pregnant mother sees the embryo and fetal heartbeat, and can relax a little.

What should I pay attention to if the gestational sac is small?

If the gestational sac is relatively small, we need to consider the past menstrual cycle. If the past menstrual cycle is very irregular, there is often a discrepancy between the number of days of pregnancy and the actual number of days, which often leads to a relatively small gestational sac. In this case, as long as the blood indicators are normal, there is generally no need to worry.

If the menstrual cycle is normal and the gestational sac is small, we also need to combine the current blood indicators and the trend of changes. If the blood increase is slow, then there is often a risk of fetal growth retardation. If the blood indicators are still acceptable after multiple examinations, the gestational sac will generally develop normally in the later stage.

In addition to understanding the size of the gestational sac, it is also necessary to understand the sac-bud difference, that is, the difference between the gestational sac and the fetal bud. If the sac-bud difference is too small, it often indicates a small gestational sac. In this case, the specific cause should be checked in time and actively treated when necessary. The common causes are similar to spontaneous abortion and recurrent abortion in early pregnancy. You can refer to patients with recurrent abortion for a systematic examination.

In addition, if the foetus is still relatively small after two or more examinations, it is recommended to actively carry out pregnancy preservation treatment to prevent adverse pregnancy outcomes.

Precautions for early pregnancy check-up

During the pregnancy preparation period, remember the duration and start time of your period. If you find that your period does not come on time, you can use a pregnancy test stick to check first, which is relatively accurate. Then go to the hospital for a blood test to measure the HCG value.

There is no need to do a special B-ultrasound to check the gestational sac. Some obstetricians recommend waiting until about 50 days to see the embryo and fetal heartbeat before doing a check. If one of your fallopian tubes is blocked or obstructed before you get pregnant, and you get pregnant without treatment, it is very necessary to check the location of the gestational sac in advance to rule out ectopic pregnancy.

During the pregnancy preparation period, it is best for expectant mothers to record their menstrual periods. On the one hand, they can calculate the ovulation period to increase the chance of conception, and on the other hand, they can accurately know the duration of their pregnancy.

Pregnancy is calculated from the day your last menstrual period began. For example, if your last menstrual period was on August 1st and ended on August 5th, if you conceived in August, then the gestational age would be calculated from August 1st.
