Pregnant for two months, ultrasound did not detect fetal heartbeat, what is the reason?

Patient's question:

Patient Gender: Ms. Li
Last menstrual period on September 26, 2005. Currently checked into the hospital for pregnancy, but fetal heartbeat was not detected during ultrasound. Please ask how long it usually takes to see fetal heartbeat after pregnancy, whether the fetus is normal, and whether it is related to previous use of birth control pills.

Doctor's answer:

According to your last menstrual period, you are now more than two months pregnant. Under normal circumstances, fetal buds and cardiac tube pulsations usually appear around the 42nd day of pregnancy, and at the latest by the 56th day. However, since you are now more than two months pregnant and there is still no fetal heartbeat, it indicates that the embryo has stopped developing. There is no longer a need to attempt to preserve the pregnancy, and an artificial abortion is necessary to prevent severe vaginal bleeding.
Recommendation: In your case, the likelihood of the embryo stopping development is high, and it is no longer possible to preserve the pregnancy. It is recommended to undergo an artificial abortion, preferably an anesthesia-free abortion, as it is less painful.
