I haven't had a period (heavy bleeding) in a year but recently, I have brown spotting for 6 days now. Not on birth control. I was engaged in oral sex and grinding with no clothes on on my partner's penis. (was grinding only the shaft and not the head), He ejaculated and some got on his stomach and some got on my legs but I didn't notice any on my vagina. We then wiped up with a dry rag and I then proceeded to rub my clit to orgasm and he had his hand on my vagina. The brown spotting started 3 days after this. I have also noticed my breasts feel a bit sore/tender now too and it would come off and on. Is it possible that I am pregnant? Today makes a week and a couple days since grinding on my partner.
