Monitoring blood HCG is around$100. Monitoring blood or urine HCG levels after pregnancy can reflect the activity of the embryo, but determining whether it is an intrauterine pregnancy and determining whether the embryo’s development matches the number of days since menopause depends on an ultrasound examination by the OB/GYN. Even if the patient has no reproductive requirements and wants to terminate the pregnancy, it is necessary to determine that it is an intrauterine pregnancy beforehand to be able to do so. Within 49 days of menopause, you can choose medication abortion, which is a combination of Mifepristone and Misoprostol, which works by killing the embryo and promoting uterine contractions to terminate the pregnancy in a way that avoids the trauma that abortion can cause to the body. However, medication abortion is not 100% successful, and some patients may experience continuous vaginal bleeding and retained embryos, which may need to be removed again if necessary.
