So I got off my birth control July 11 because I had bleed through out the whole pack. On July 19th, 20th, and 21st I had unprotected sex. I started having really bad back pains around my waist area, slight cramps and slightly nauseous on the 23rd. I ovulated the 25th. Since the day I began ovulating, every time I sit down to pee I bleed vaginally. The blood isn't normal period blood. I don't bleed at all unless I sit down to pee. Someone help
