How many months of pregnancy does the fetal heartbeat have?

Color Doppler ultrasound examination showed embryonic bud and fetal heartbeat at around seven weeks of pregnancy. The early, middle and late appearance of the embryo bud and fetal heart rate are closely related to the baby's development. In clinical medicine, the gestational age is calculated based on the expected date of delivery. In women with menstrual disorders, the embryonic bud and fetal heartbeat may not be visible during the seventh or eighth week of amenorrhea. I think it means that the baby's development is abnormal, just considering the late pregnancy. This means that although the menopause period is long, the actual pregnancy period is short. The absence of fetal bud and fetal heartbeat does not necessarily mean that the embryo has stopped developing. You can wait one to half a month before returning for a follow-up visit.

Normally, a woman's cycle is about 28-30 days, usually between 6-8 weeks of pregnancy. Through B-ultrasound, the gestational sac can be clearly seen in the dilated uterus, and the fetal bud and fetal heartbeat can be seen in the gestational sac. However, there are certain individual differences, because the length of each woman's menstrual cycle is different, as short as 21 days, as long as 35 days, and some may be longer. If the menstrual cycle is more than 35 days and the pregnancy is 6-8 weeks, it is possible that the fetal heartbeat is not seen. However, it cannot be completely confirmed that the fetal sac is incompletely developed. You can recheck the B-ultrasound in one week. If the fetal heartbeat is seen, it means everything is normal. If the fetal heartbeat is not seen after 60 days of pregnancy, it means that the fetal sac is underdeveloped and termination of pregnancy may be considered if necessary.

After pregnancy, for women with normal menstruation, if the normal menstrual cycle is 28-30 days, the fetal bud and initial vascular heartbeat will appear at about 7 weeks of pregnancy, the fetal bud and fetal heartbeat will appear at 9 weeks of pregnancy, and the amniotic cavity cyst of the fetus will appear. The fetus and fetal attachments, including the embryo and amniotic fluid, will be formed at about 12 weeks of pregnancy. If the fetal bud and initial blood vessels are not detected at the gestational week when they should appear, further follow-up is required to consider the possibility of incomplete development of the test tube embryo.

The main purpose of color Doppler ultrasound examination in early pregnancy is to confirm intrauterine pregnancy, rule out ectopic pregnancy and trophoblastic disease, estimate gestational age, and rule out pelvic tumors or uterine abnormalities. When the menstrual period is 35 days, a circular or oval gestational sac can be seen in the uterine cavity. When the menstrual period is 6 weeks, the fetal heartbeat and fetal heartbeat can be seen. If the fetal heartbeat and fetal heartbeat are not seen for more than 7 weeks, it means that the test tube embryo has stopped growing. You should go to the hospital for an abortion as soon as possible to avoid intrauterine infection after a long time and affect the next pregnancy. If everything is normal, you must do a good job of prenatal check-up. Regular prenatal check-ups are very important.
