The absence of vaginal discharge cannot be used as a basis for determining whether a woman is pregnant or is about to have her period. Generally speaking, after pregnancy, due to the increase of estrogen secretion in the body, the vaginal secretion function is vigorous, the vaginal secretion will obviously increase, and there will not be no vaginal secretion phenomenon. If a woman suspects that she is pregnant, she can use pregnancy test paper to test or go to the hospital for blood tests. Before a woman’s period, due to changes in hormone levels in the body, vaginal discharge will also increase significantly and there will be no discharge from the vagina. Many women experience breast tenderness or tingling before their period, and sometimes have pain or swelling in the lower abdomen. If you experience a decrease or absence of vaginal discharge, you should consult your gynecologist.
