If you have been having brown discharge after pregnancy, first of all, ultrasonography should be performed to determine that it is a normal pregnancy in the uterine cavity and to exclude ectopic pregnancy and gestational trophoblastic disease due to pregnancy, such as hyperemesis gravidarum. Secondly, it is important to determine whether the development of the embryo matches the number of days of menopause and to exclude the possibility of vacuolated pregnancy and embryonic arrest. If the ultrasound examination shows intrauterine pregnancy and the embryo development is consistent with the number of days of menopause, consider the possibility of pre-eclampsia and recommend fetal preservation treatment. Pay attention to rest, don’t participate in heavy physical labor, keep your mind calm, don’t be overly nervous and overly excited. Progesterone treatment is recommended. You can take oral dydrogesterone or progesterone capsules, or you can inject progesterone injection intramuscularly.
