so me and my boyfriend have been having constant sex for a month every night. neither of us minded if I got pregnant. last week I didn't feel any signs of my period coming on, which for me is weird because I always feel them coming. I kept feeling like something wasn't right. day before my period I took 2 tests but neither came out positive. yesterday my period hit me like a freight train, but it was bright red and twice as heavy as normal,like over flowing my super tampons. I went through them every hour. I also woke up nauseous, with lower back pain near my spine and severe cramps, like scale from 1 to 10 they were 10. I could barely move with out crying. this morning I wake up still lil nauseous and some back pain and cramping but the blood is still bright but extremely light. this off feeling is gone but its left me feeling confused.
