I was intimate with my boyfriend -no penetration occurred. Just rubbing his penis on my vulva. He did not ejaculate near my vulva. My next period was about 4 days late (I'm regular and I'm on the pill, although I'm not sure I was taking it correctly back then) which made me think I could be pregnant. It has made me very anxious, but apart from very vivid dreams I do not have any symptoms. I have had 2 heavy periods since and I had a negative test (about 8 weeks afterwords). Could I be pregnant?
