I went off of birth control, and I got my period right after I had sex. It had like a watery content to it. I last had sex on Mothers Day. I was a month and half late for my period. But now I'm having extremely bad pains in my lower back, and in my pelvis region. I've tried taking Midol, Tylenol Extra Strength, Ibuprofen, Motrin. Nothing is taking this pain away. And its getting worse. My legs have even gone numb. My period now is SUPER heavy, and a beat red color. I get super sick after I eat. And I just don't know what to do. Am I having a miscarriage?
