Okay I thought I was just starting my period because when I wiped there was blood then it got a little heavy so I put a tampon in. After I pulled the tampon out I didn't put another one in Because there wasn't enough blood. Usually on my periods I where tampons and pads just for protection because I have a heavy flow. Then the second day came and in the morning I wasn't bleeding at all. The afternoon I had just a spot of blood on my pad. Then it stopped again. But everything I go to the bathroom and wipe.there is a llight red or pink streak on my toilet paper... I am sexually active. What is this?
