After pregnancy, in addition to strengthening nutrition, you should also pay attention to the following issues: 1. Keep your vulva clean, wash it with water twice a day, and wear loose cotton underwear, not tight-fitting outer pants, such as jeans, which affect the blood circulation in the pelvis. 2. In the early stages of pregnancy, you should not have sex in the first three months, because sex can cause the uterine wall and the gestational sac to The first thing you need to do is to check your nipples, and if you have mild nipple invagination, it is recommended that you gently pull your nipples after applying warm compresses with warm water every day, insisting on 15 strokes each time, twice a day, so that the nipple invagination can be improved, which is beneficial to the newborn’s breastfeeding.
