Can I see the gestational sac after 38 days of amenorrhea?

Many women are very anxious during the pregnancy preparation period, hoping that they can get pregnant as soon as possible. Therefore, after some pregnancy symptoms appear in the body, they worry about whether they are pregnant. If menstruation has not stopped for 38 days, women may have the chance of pregnancy, and they can go to the hospital for examination at this time. So can the fetal sac be seen after 38 days of amenorrhea?

Can the fetal sac be seen after 38 days of amenorrhea?

1. On the 38th day of pregnancy, the fetus grows to 0.4 cm and enters the test tube embryo stage. The amniotic cavity expands, initial cardiovascular and cerebrovascular diseases appear, and heart beats may be present. B-ultrasound can show a small gestational sac, which occupies less than 1/4 of the uterine cavity, or the embryonic bud and fetal heartbeat can be seen from it.

2. If you are 38 days pregnant and no gestational sac is seen on B-ultrasound, there is no need to worry too much. It may be late pregnancy. You can wait a few days to go to the hospital for a follow-up check. In addition, to check the blood HCG value, further blood tests are needed to see whether the blood HCG value is in the state of pregnancy, which can confirm the diagnosis and rule out ectopic pregnancy.

3. An empty gestational sac means that the test tube embryo has not developed well. There are many reasons, such as poor sperm quality and environmental factors that affect the development of the embryo. Sometimes an empty gestational sac will appear due to late sperm and egg combination. Therefore, couples should improve the quality of sperm, refrain from smoking and drinking, increase physical exercise, and maintain a good mood during the active preparation for pregnancy.

How to calculate the fetal sac?

1. The gestational sac is only seen in the early stages of pregnancy. For women with standard menstruation of 28 to 30 days, the gestational sac can be seen in the uterine cavity by B-ultrasound after 35 days of amenorrhea. The diameter of the gestational sac is 2 cm at 6 weeks of pregnancy and about 5 cm at 10 weeks of pregnancy.

2. The location of the gestational sac in the fundus, front wall, back wall, upper end, and middle of the uterus are all normal. It is normal for the gestational sac to be circular, oval, and clear in shape. If the gestational sac is irregular in shape, unclear, and located at the bottom, and the pregnant woman also has abdominal pain or vaginal bleeding, she may have a miscarriage.

3. Use the fetal sac to calculate (length, width and height)/3 25, mm, the result is the number of days, the fetal bud and fetal heart rate are 6.5, cm long, which is the number of weeks. On the other hand, at 4 weeks, the gestational sac is not large and ultrasound cannot clearly show signs of pregnancy. At 5 weeks, a small gestational sac can be seen on B-ultrasound, which occupies less than 1/4 of the uterine cavity, or the embryonic bud and fetal heartbeat can be seen from it. At 6 weeks, the gestational sac is clearly visible on B-ultrasound, and the embryo, fetal heart rate and fetal heart rate can be seen. At 7 weeks, B-ultrasound clearly shows the embryo, fetal heart rate and fetal heart rate, and the gestational sac occupies about 1/3 of the uterine cavity.
