It happens sometimes: If worried, one's doctor can check to see if there is any medical issue, if a woman has mild menstrual-related symptoms. Many women have some variation of their mucus discharge, their periods, or a missed period on occasion. Some women feel normal after a few days, but others have bothersome symptoms and need follow-up with their doctors. A home urine pregnancy test may be done if needed.
