So my boyfriend and I had unprotected sex about two months ago and when he came it got around my vulva. I wasn't to concerned at first but now I am. I haven't gotten my period in 27 days. I was suppose to get it on May 28 and on June 16. I was discharging and it looked like I was spotting a little like a week ago. I took two pregnancy test about 2 weeks ago and they both came out negative.. I'm absolutely terrified and I don't know what to do, any suggestions?
