Biochemical pregnancy does not require menstruation. Biochemical pregnancy is a spontaneous miscarriage that occurs in the very early stages of pregnancy, and many patients are unaware of biochemical pregnancy, thinking it is an ordinary period. Only some of them are more sensitive or do the examination in time to find out that it is a biochemical pregnancy. During biochemical pregnancy, the gestational sac in the uterus can flow cleanly and the uterus generally recovers better. After miscarriage, you do not need to do a small month, but you still need to pay attention to rest, avoid strenuous exercise, and it is recommended to eat light, high-protein food, and do not eat spicy, stimulating, blood-activating food.
