My boyfriend and I were dry humping on Saturday March 7. I had no underwear on but he had on his jeans with no boxers. He didn't cm. But I was aroused and wet. And i got my period Monday March 9 right on time, then Tuesday my period suddenly stopped. I'm very worried and paranoid about this. Idon't know if my period stopped due to stress or what.i I took a pregnancy test at home yesterday and it came out negative. I'm worried becausemy period usually lasts from 4 to 5 days. I'm going to get on birth control this weekend and be very careful about what I do. He also fingered me and I don't know if he possibly did it too hardy o hurt me down there to make my period stop. This is a silly question but I'm so worried and anxious. I want serious answers please not some tatistic. Keep in mind that he did not cm, i don't know if the precm could go through his jeans into me. Thanks.
