I had a baby in December 07, and I hadn't had sex since Oct 2007. I had sex about a week ago, it was really painful to start out even though I was aroused, which I know can be normal after having a baby. During sex I started bleeding, it wasn't heavy or anything like that, it was light pink spotting, and it was mixed with vaginal fluids from when you're aroused (if that helps). There was no pain or anything like that, and it didn't have any odor to it. I noticed it for a few hours when I wiped, and by that time it was barely noticable, by morning it was completely gone. My question is could it be from rough sex (being it was my first time in a long time). I've been tested for STD'S, all negative. Any insight would be great, thanks.
