I have been having cramps I already had what I thought was my period. But when I actually got to thinking about it. The supposed to be period I had didn't last long. Just a couple of days. I have never actually had a burning cramping type feeling like this before. I am seriously wondering if I am pregnant. I was just wondering what all kinds of implantation bleeding everyone has had. This is not exactly any kind of cramp I ever had before. I never been pregnant yet but me and my boyfriend do have unprotected sex. I just never actually felt this feeling before.
