My boyfriend and i have had sex multiple of times. Most of the time we are protected. A few times it happens with out protection. ABut when we use no protection, he always "pulls out" before he ejaculates. Earlier after having sex, it wasnt rough or anything and we used a condom. But after going to the bathroom, when i whiped myself, there was a little pink spot on the toilet paper. I was like okay. So i got another clean piece and whiped it again. And it was there again. My period isn't due till the 23rd. And im starting to worry. Any help?
