A "friend" of mine and I had sex on march 30th 2 days after I was off my period. We used a condemn but it was 3 months old and was in his wallet. On April 12th I had a very, very light period that only lasted a couple days. In May I didn't have a period, and I haven't this month yet either. I was usually regular and extremely heavy. I'm not sure if I'm pregnant or if this could be something else. Any ideas?
