Hello, a friend and I had sex on March 1st. My period ended Feb 27th. Well today March 10th I am having period like cramps. My friends are telling me I am being paranoid because I do not want a child right now, but this cramping is something I can not ignore. My period is not due again until around March 20th. Oh also... we did use condoms. And nothing happened, meaning no breaking, slipping, or leaking. I know there is always a chance, but is it more likely Im not, than I am?? Thank you. So so Much!
