Hello,
I was with my boyfriend and we did a lot of dry humping, fingering and oral sex. He was clothed, only in his underwear and t shirt while I wasn't. Right before my period was due (two days after we did thus) I experienced light , pinkish bleeding that only lasted a few hours. I took a pregnancy test the day after and it was negative. What are the chances that I am pregnant and that this was implantation bleeding?
