What is the reason for the large gestational sac?

In the early stages of pregnancy, if you want to see if the baby in your belly is healthy, you can only determine it by testing the gestational sac. After all, at this time, the baby has not yet formed a gestational sac, which is its precursor. Sometimes the gestational sacs of many pregnant women are larger, so what is the matter with the large gestational sac?

It may be that the ovulation period is early, which causes the gestational sac to be larger. If there is a normal fetal heartbeat and fetal bud, the larger gestational sac will have no effect on the fetus. If there are no other abnormalities, there is no need to worry. It is recommended to go to the hospital for regular prenatal check-ups. At 8 weeks of pregnancy, the size of the gestational sac is 46*20mm, which is mostly within the normal range. If two fetal buds are found, then the gestational sac is too large and there is a possibility of twins. Experts recommend taking active rest and paying attention to health care during pregnancy. They also recommend going to the hospital regularly to check the condition of the fetus.

The gestational sac is only seen in early pregnancy. For women who have regular menstruation of 28 to 30 days, after 35 days of amenorrhea, the gestational sac can be seen in the uterine cavity by B-ultrasound. The diameter of the gestational sac is about 2 cm at 6 weeks of pregnancy and about 5 cm at 10 weeks of pregnancy. It is normal for the gestational sac to be located at the fundus, front wall, back wall, upper part, or middle part of the uterus. It is normal for the gestational sac to be round, oval, and clear. If the gestational sac is irregular, blurred, and located in the lower part, and the pregnant woman also has abdominal pain or vaginal bleeding, she may have a miscarriage.

The gestational sac is also a product of ectopic pregnancy. The fertilized egg fails to enter the uterus at 7 days due to certain factors such as inflammation and adhesion. Ectopic pregnancy usually causes heavy bleeding, and generally the fetus cannot survive. The baby's mother herself was having an intrauterine pregnancy, but due to poor development of the uterus, the gestational sac broke through the weak top of the uterus and entered the abdominal cavity. The villi around the gestational sac sought nutrients everywhere in the abdominal cavity and then supplied them to the fetus through the placenta. Usually, such a fetus will die within two months because it has no protection from the uterine environment and lives in an extremely harsh environment with poor nutrition.
