Can I see the fetal heartbeat and embryo at 40 days of pregnancy?

Generally, the embryonic bud and fetal heart rate cannot be seen at 40 days of pregnancy. Under normal circumstances, the embryonic bud and fetal heart rate can only be seen under B-ultrasound examination at around 7 weeks of pregnancy. Generally, the gestational sac can be seen in the uterine cavity 35-40 days after pregnancy, but there are also cases where the fetal heartbeat appears relatively late. At this time, you can wait for another week or 10 days for a follow-up check. If there is still no fetal heartbeat, the child cannot be kept. In addition, during pregnancy, you must maintain a happy mood, regular life, and ensure adequate sleep, which is beneficial to the development of the baby. You also need to go to the hospital for regular prenatal checkups.

After a woman becomes pregnant, the embryonic bud and fetal heartbeat can usually be seen 6 to 7 weeks after menstruation. If the fetal heartbeat and embryonic heart rate are not detected during the B-type color ultrasound examination at 7 weeks of pregnancy, it may be that the test tube embryo has stopped developing; it can be observed until 8 weeks of pregnancy. If the B-type color ultrasound still cannot detect the embryonic heartbeat and embryonic heart rate at 8 weeks of pregnancy, and the yolk sac is not seen. If it is clear that the test tube embryo has stopped growing and developing, it is recommended to go to the obstetrics and gynecology department of a regular hospital immediately and follow the doctor's advice to prevent intrauterine infection after a long time from affecting the next pregnancy. If the prenatal examination results are normal, pregnant women should remember to go to the hospital regularly for prenatal checkups.

Under normal circumstances, the embryonic bud and initial vascular heartbeat will be found more than 42 days into pregnancy. However, for women with normal menstrual disorders, the expected date of delivery is usually difficult to infer, and the number of days of pregnancy should be calculated based on the gestational sac, fetal bud size or top-to-rump diameter shown in the early stages of pregnancy. The fetus will appear after 63 days of pregnancy. For women with regular menstruation, if the embryo bud and initial vascular beats are not found within 49 days after menstruation, the growth and development of the fetus can be judged according to the levels of chorionic gonadotropin and progesterone.

The appearance of fetal heartbeat and embryonic heartbeat is closely related to women's physiological cycle. The fetal heartbeat and fetal bud are gradually produced during the development stage of sperm and egg combination. The first two weeks are called pregnant egg. Due to the growth and development of the test tube embryo, the gestational sac will be produced 30-40 days after the menstruation, the embryonic bud and fetal heart will be produced 40-50 days after the menstruation, and the fetal heartbeat will be produced 50-60 days after the menstruation. If a woman has a menstrual cycle of about 28 days, the fetal heartbeat and embryonic heartbeat can be seen at the latest 49 days after menstruation. If the fetal heartbeat and fetal heartbeat are still not visible at this time, fetal growth retardation should be highly suspected. If a woman's menstrual cycle is delayed, the time to see the fetal heartbeat and fetal heartbeat will exceed 49 days. If a woman has irregular menstruation or forgets her due date, she can calculate her due date and delivery date based on the time when she sees the fetal heartbeat and fetal heart rate on B-ultrasound.
