The size of the gestational sac varies from person to person

After many pregnant mothers go to the hospital for a check-up, the doctor will give them a B-ultrasound form and let them see the gestational sac marked on it. They will feel confused because they don’t understand what the data means. In fact, pregnant mothers can also learn more about the size of the gestational sac in life. The following article will introduce you to the comparison of gestational sac sizes to see what the differences are.

The location of the gestational sac at the fundus, front wall, back wall, upper part, and middle part of the uterus are all normal; round, oval, and clear shapes are normal; the fetus has not yet formed at that time, but the fetal heartbeat is already there when the embryo bud appears. The embryo implants into the endometrium in the second week. When it develops to the second germ layer, a large cavity called the primary yolk sac appears on the ventral side of the embryonic disc. The yolk sac continues to shrink and degenerate during embryonic development, but the extraembryonic mesoderm on the wall of the yolk sac is the earliest origin of the formation of blood cells, blood vessels, and primitive germ cells - the gestational sac, where the fetus will grow in the future. The size of the gestational sac is a sign of the size of the month of pregnancy, the larger the gestational sac.

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 it to be round, oval, and clear in shape; if the gestational sac is irregular in shape, blurred, and located in the lower part, and the pregnant woman also has abdominal pain or vaginal bleeding, she may have a miscarriage.

In fact, the size of the gestational sac varies from person to person. The "person" here does not refer to babies of different genders, but to the pregnant woman herself, or the fetal development affected by the pregnant mother's personal circumstances.
