After three days of miscarriage, you can take a bath. After the fetus and placenta are delivered, there will be a small amount of residual uterine cavity, so the uterus will be cleared, and the amount of vaginal bleeding is relatively large in the first three days after the cleansing operation, and the amount of vaginal bleeding will be reduced after three days. After three days of miscarriage, you must choose to take a shower, but not a tub bath. After miscarriage, the vaginal bleeding lasts for about 10 days, so if the bleeding is not clean and you choose to take a tub bath, it will easily lead to infection. Blood is the best petri dish for bacteria when women bleed vaginally, and the cervical opening of women is looser after the operation of birth and uterus removal, so it is especially easy for bacteria, viruses and various microorganisms to go up through the vagina to the pelvic cavity and cause infection when taking a tub bath.
