I am 17 years old. I was on birth control for five months and have regular periods. Today my period came a week and a day early. The blood is a thick slime and clumpy, and very dark red nearly black. I have been getting very bad pain in my abs, kinda like craps but I never had them this bad. I've been getting them since Thursday, it is now Sunday. Today I fell twice from how bad the pain had gotten. I have had unprotected sex and I think I'm having a miscarriage, but my mom thinks different. Am I?
