I'm have a scare me and my boyfriend messed around on January 30 2 days after my period but we never had intercourse but grinding was involved with no clothes and I'm scared because it was 7.4% that I could get pregnant and now I'm ovulating and I have a little blood now I'm scared out my mind. The only person I have to talk about this with is my boyfriend.... NEED YOUR OPINION could I be pregnant or am I just scared myself
