When is the baby's fetal heart formed at the latest?

The doctor didn't know her condition, saying that there was no fetal heart germ after three months of pregnancy. This is unhealthy embryonic development and pregnancy should be terminated. Later, after careful communication with the doctor who did B-ultrasound, the doctor told her to come back in a week, and there might be fetal heart germs. For pregnancy, the formation of fetal heart germ is the key sign of fetal development success. Generally, a fetal sac will be formed after one month of pregnancy, and a embryo will appear ten days later. It takes more time for the fetal heart to appear. The menstrual cycle is long, generally the follicular phase is long, and ovulation is about 2 weeks before the next menstruation. So look at the fetal heart should be 4-5 weeks after ovulation.

If the menstrual cycle is usually long and ovulation is late, then the time of embryo germination and the time of seeing gestational sac in uterus may be relatively late. Germ: The embryo before the second month of pregnancy is also called germ. B-ultrasound is wonderful. You can see that the embryo bud is normal. If there is a fetal sac but no germ, then the last menstrual error is ruled out and the ovulation period is delayed, indicating that there may be problems with the embryo. It is recommended to follow the doctor's advice, and there is no need to blindly protect the fetus.

My wife has everything when she is 6 weeks old, but her menstruation is 27 days, which is very accurate. If a woman's menstruation is not accurate, this time is uncertain. It's safe to go for 8 weeks. Basically, my cycle will be very long, once every 36-39 days. I felt pregnant 37 days after my last period, and I had a yellow sac 43 days later. On the 66th day after my last vacation, B-ultrasound showed that I had a fetal heart embryo bud of 7 weeks and 4 days.

Generally, fetal heart germs can be seen after 5-6 weeks of pregnancy, and some of them are normal if delayed. If the menstrual cycle is long, wait a little longer and it may be delayed. After two months (60 days), you will basically finalize the design. There is. No, there is! Clear intrauterine and ectopic pregnancy, put an end to the occurrence of ectopic pregnancy. At this time, because the days are too short, only the gestational sac can be seen. If the fetus is well developed, you can still see the yolk sac, but it is normal not to see the germ. You can check the color Doppler ultrasound again in a week or two.
