Breast cancer patient in remission. Completed chemo dec. Had pre- menopausal symptoms and menstruation stopped during chemo. Started having cycle again in december...3 says. January...5 days. February was late so first week of march 6 days. April...5 days. This month's cycle has been going pretty heavy for 10 days already. I'm having to wear a super tampon and a pad and changing every couple of hours
