Hi, I'm a 16 (nearly 17) year old girl. Recently I had sex with my longtime partner for the first time. The next day I realised I had some brown discharge in my panties. This went on for 5 days and then stopped. Nearer the end of the five days though the discharge looked more of a dark brown/red colour. I don't count the days when my period should be which isn't helping the situation. I'm really worried because I don't want a baby! Not yet anyway, I'm too young! Me and my partner DID use protection but still I'm worried it split during intercourse.
