I am 17 and I had unprotected sex with my boyfriend on thursday (the 8th) and we used the pull-out method, but he came on my clit. We knew we were risking pregnacy, and we are fine with that, we actually sort of want to have a baby, but anyway...It's been 2 days and today there was spotting on my underware and dark brown blood when I wiped, but there has been no more blood on my underware, but still a little when I wiped later on. I heard it is too early for implantation bleeding but it is also way too early for my period but also my last regular period was in october and I only spotted in november, but I took a preg. Test early last week and it was negitvie. I am very confused. Could it be implantation bleeding or not? Or could I even be pregnant, what is the chance? :?
