Can I see the gestational sac on ultrasound at 38 days?

Women need regular prenatal checkups after they become pregnant, and the status of the gestational sac can be seen through B-ultrasound in the early stages of pregnancy. The conditions of the gestational sac will be different at different times of pregnancy. The 38th day of pregnancy is in the early stages of pregnancy, and many women want to know whether a gestational sac has been formed and the status of the gestational sac. So can the gestational sac be seen through ultrasound at 38 days of pregnancy?

1. Whether the gestational sac can be seen on the 38th day of pregnancy depends on each person's menstrual situation. For example, each menstruation will come 5-7 days in advance, that is, the monthly cycle is 25-28 days. The gestational sac can be seen on the 38th day of pregnancy. During a black and white B-ultrasound examination, the gestational sac may be relatively small, possibly between 0.8-1.0. At the same time, if the menstruation is delayed by 7-10 days each time, the cycle is relatively long, and the gestational sac may not be seen during the 38-day check. Because of the delay in the menstrual cycle, the ovulation period may also be delayed, and implantation will be late. The gestational sac may not be seen at 38 days. It is recommended to go to the hospital for a black and white B-ultrasound examination around 45 days of pregnancy.

2. If a woman has a normal menstrual cycle, the menstrual cycle is about 28 days. If the fetus develops well after 38 days, the gestational sac can be clearly seen through vaginal ultrasound. But under normal circumstances, if you are planning to have a baby, the general hospital may perform an abdominal ultrasound, and you need to hold your urine to do the abdominal ultrasound. Some instruments are not very precise, or the bladder is not very well filled, so the gestational sac may not be seen, and you can only see the thickened endometrium. However, under normal circumstances, you should see a small gestational sac. At this time, you basically cannot see the fetal heart or fetal bud because the pregnancy is a little too early. It is recommended to do an ultrasound around 45 days of pregnancy under normal circumstances. If the development is normal, the fetal heart and fetal bud can be seen. It is better to do it at this time.

3. It is possible or possible that nothing can be seen during an ultrasound at 38 days of pregnancy. There are two situations. In the first situation, we can see pregnant women with regular menstruation. For pregnant women with regular menstruation, the menstrual cycle is generally 28-30 days, and the urine test will be positive if the menstruation is amnesia for more than 30 days. In this case, a gestational sac can be seen in the uterus under B-ultrasound 35 days after menstruation. For pregnant women with irregular menstruation, irregular menstruation will lead to delayed ovulation and then delayed conception. The fertilized egg will develop late, so the urine test will show results late. Pregnancy may not be detected for more than 30 days after amenorrhea. Sometimes a positive urine test may not be found until 40 days after amenorrhea. The gestational sac appears relatively late at this time, and may not be visible under B-ultrasound 38 days after menstruation. Therefore, whether the gestational sac can be seen under B-ultrasound at 38 days of pregnancy depends on whether the pregnant woman's menstruation is regular, whether she ovulates normally, and whether she conceives normally.
