I'v missed my last period and I'm just after staring to get brown discharge yesterday at first I thought it was my period but it was only light and a brown colour and I was'nt sure!. But I don't know what I should do because I'm only 12 and I'v never had sex so I don't know why I'm missing my period the only reason I can think of is that I have started doing a lot of sports lately! Pleas help! Im very concerned / scared! :(:confused::(:confused::(PLEASE HELP!
