Last month my period started off normal-the light bleeding, and minor menstrual pains. The second day, I started clotting. The clots were sometimes small, but sometimes large. It didn't hurt or anything to pass them, it just felt wierd, and the clots were coming about every half hour or so. The next day was back to normal, and I said if it happened again I would ask a doctor. Yesterday I started my period, and it was normal again, and today it started clotting again. Do I have something wrong with me?
