Me and my boyfriend were messing around and we never fully did the deed. He rubbed is thing on my thing, this happened July 2nd at 1 am ish, I took the plan B pill on July 4, it is now July 17th. I believe I started my period two days ago but I am scared if it is just implantation bleeding, or if it is actually my period. It was really light the first day and then I was bleeding more yesterday and today it is more thicker and a lot heavier when I wipe. I did have my wisdom teeth removed July 12 and the only thing that I have felt is feeling nauseous all day yesterday but I have been on pain meds and antibiotics. Am I pregnant because I have been so worried over these days. Help please.
