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 no fetal heartbeat was detected during the ultrasound. Please ask how long it usually takes to see a fetal heartbeat after pregnancy, whether the fetus is normal, and whether it is related to the 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, now that you are more than two months pregnant and there is still no fetal heartbeat, it indicates that embryonic arrest has occurred, and there is no longer a need to attempt to preserve the pregnancy. You should consider an induced abortion to avoid the risk of heavy vaginal bleeding.
Recommendation: In your case, the likelihood of embryonic arrest is high, and it is no longer possible to preserve the pregnancy. It is recommended to undergo an induced abortion, preferably an anesthesia-induced abortion, as it is less painful.
