My boyfriend and I dry humped and he ejaculated, but he had pants and underwear on and I had underwear on. I haven't had my period since July 16th, it is now August 31. I had walking pneumonia at the time. Ive also been extremely stressed with school starting and finances. I've had cramps for weeks, but no period. Over the past week I've had sharp pains in my ovaries and intense pain in rectum at times. Am I pregnant? I know that should be impossible but I'm so paranoid. Any ideas what else could be going on?
