After pregnancy, women need to undergo B-ultrasound examination. In the B-ultrasound sheet, not only will it show whether the fetus is pregnant in the uterus, but also the size and shape of the gestational sac. Of course, the size and shape of the gestational sac will change at different gestational weeks. So, how do you look at the shape of the gestational sac?
The shape of the gestational sac usually varies from circular to elliptical to elongated, depending on the gestational age and the pregnant woman.
The gestational sac is only visible in the early stages of pregnancy and gradually develops into an embryo, then gradually into a fetus. For women with regular menstrual cycles, such as a cycle of 28-30 days, the gestational sac can be seen through ultrasound examination 35 days after the cessation of menstruation. At 6 weeks of pregnancy, the diameter of the gestational sac is approximately 2 centimeters, and at 10 weeks of pregnancy, the size of the gestational sac is approximately 5 centimeters. The size of the gestational sac varies depending on the time of pregnancy. Of course, the size of the gestational sac also varies among pregnant women.
The position of the gestational sac is generally located in the upper and middle part of the bottom of the uterus, and may also be on the anterior or posterior wall of the uterus. These positions are normal, and the shapes are mostly elliptical or circular, which are very clear. If the shape of the gestational sac is irregular or blurry, and the pregnant woman also experiences vaginal bleeding and abdominal pain, it indicates that she may have to have a miscarriage.
