Period beggining date- July 12, 2012. Period ending date- July 17, 2012. Last day of unprotected sex- July 25, 2012 Day I started my birth control after I had been off it for a couple months- July 26, 2012 A few days before I had unprotected sex, I had the runny discharge that looks like egg whites come from my vagina .I have been having cramps , and I am hungry a lot. I have no idea how long my menstrual cycle is. Could this be side effects of the birth control? Could it be my period coming up? Could I be pregnant? side
