Hi, I'm 14 years old and I haven't started my period. I think I'm going too soon though, I have been getting white/clear discharge for a few months now and 2 days ago I got browny discharge, is this normal? And I'm also really worried that I'm going to come on, because today it's Thursday and on Monday I'm going swimming with dolphins. I'm really worried that because I've never had my period before and I won't be able to use a tampon and won't be able to go this is a once in a life time opportunity for me and I'm really scared I can't go. Is there any advise anyone could give me or anything I could do?x
