So about 2 and a half months ago I had engaged in dry hump. I had on underwear and veryyyy thin pain of skily p.js and he had in his basketball shorts. His p was rubbing against my v but we had clothes on as a barrier. After we were done I felt my clothes were a bit damp. I'm not sure if he pre-cmed or ejaculated or nothing at all, but let's say he ejaculated and given the clothes we had on is there a risk of pregnancy? I'm really scared please help!! Also during dry hump I had many assignments and tests so my sleeping and eating schedule was all messed up! After about 2 weeks or so of the day we had dry humped I got my period. However it only Lasted for two days which has never happened before. Then the next month I got my period again (they are very irregular btw) which lasted 5 days which is normal for me but the flow was very light almost as if spotting, the color was brownish and sometimes like pink, no cramps. No clots, almost watery. I was very stressed!!!! Because all I could find was implantation bleeding online. I'm very scared because I don't want to be pregnant. In addition I also did a clear blue plus home pregnancy test which came up negative both times. But I've also read online about false negative tests!! And I'm just very stressed. I've been feeling bloated lately. Like my stomach looks big!! So based on my dry hump activity is there a risk? Please help and sorry for the length of the question!
