If you don’t get your period before wiping, it may be due to pregnancy, preeclampsia, ectopic pregnancy, endocrine disorders and so on, which can be treated by fertility preservation treatment, surgical treatment, supplementation of estrogen and progesterone and so on. 1. Pregnancy: After pregnancy, when the embryo is implanted and breaks through the uterine lining, there may be a small amount of bleeding, which is a normal phenomenon without treatment. 2. Pre-eclampsia: When the embryo is unhealthy or the progesterone is low, there may be a small amount of bleeding, which can be treated with progesterone capsules and other medications to keep the pregnancy alive. 3. Ectopic pregnancy: If the embryo is located in any place other than the uterus, it is ectopic pregnancy, which needs to be diagnosed in time and hospitalized for conservative treatment or surgery. 4. Endocrine disorders: endocrine disorders may cause dribbling menstruation, irregular menstruation, etc., and need to be treated with estrogen and progesterone drugs, such as estradiol valerate and dydrogesterone. There may also be other reasons for the lack of menstruation, which need to be clearly diagnosed by a doctor, who will formulate an individualized treatment plan, do not blindly use drugs to avoid adverse consequences.
