Confused

Last month I got what I think is my period. First few hours it was light then heavy. Lasted 5 days as heavy and then I had light like spotting for 3 days. It was all brown. A week before this my body started cramping. My breasts hurt. After my period I had nausea for almost all three weeks. Sharp pain. Pins and needles on my abdominal area and back. Last month (before period January) Had protected sex around ovulation and he took it out (he was wearing a condom the whole time). Anyone? Now I'm supposed to be getting my period but I don't feel the usual pms or cramps. Just pins and needles and increasing discharge.
