So I'm 16 and me and my boyfriend have been having sex for a little while now and I told him that we need to be using a condom, so he went and got some. Well that night we used the condom and it burned really bad, so I made him take it off and we went on with out it. Everything was good until the next morning I was bleeding, I thought it was just spotting cause I had just started taking birth control about a month ago, but it got heavier like a period and it would change from a brown color to a pink color each time I checked it. Well as period only last a week and I've been bleeding for about 2 weeks now it's being to scare me, and I think I have a small bladder infection or somthing, what do you think?
