The main function of estradiol is to promote the growth of the endometrium, which provides a good environment for the fertilized egg to settle and for the embryo to grow and develop during the early stages of pregnancy. If estradiol is low, the endometrium is too thin or grows slowly, which can easily lead to premature miscarriage. A drop in estradiol needs to be monitored for embryonic development and can be left untreated if there are no abnormalities. Estradiol is mainly used to promote the growth of the endometrium, and it is important to check progesterone and progesterone, as well as chorionic gonadotropin. If progesterone is low, it can cause miscarriage, and the HCG test is constantly increasing after pregnancy, doubling in 48 hours, and if it does not double in 48 hours or if there is a small amount of vaginal bleeding and abdominal pain in the early stages of pregnancy, there may be signs of miscarriage. If estradiol is low, it is recommended to supplement with Glivec, which can be taken orally and reviewed regularly. The above questions are for reference only. Please refer to the doctor’s instructions for specific medication and treatment.
