Aunt refers to menstruation, and it is not possible for menstruation to come early in the month of pregnancy. The process of menstruation is the shedding of the uterine lining, which is related to the level of estrogen and progesterone in the body. The main reason is that the level of progesterone decreases, which can’t support the growth of the uterine lining, and the uterine lining is shed. After a woman becomes pregnant, the level of progesterone in her body will continue to rise, at which time the endometrium will no longer shed normally, so she will not have a period after pregnancy. If a woman experiences menstruation after pregnancy, consider that it is not true menstruation but vaginal bleeding, which may be related to preeclampsia, and should also be alert to the presence of ectopic pregnancy, all of which can cause vaginal bleeding, which can be mistaken for menstruation by some people. Vaginal bleeding after pregnancy, you should go to the hospital in time for examination, to clarify the cause of the symptomatic treatment, to avoid delaying the condition.
