I'm 14 years old and my period is about 3 months late and I have never had sex or done anything with a guy! I have a brother and we use the same shower (not together ) but is it possible for me to be pregnate? I haven't told my mum becuse I'm scared of what she will say. Can someone please help me! About a week ago I had some blood in my knickers but nothing after that and a while ago I had brown discharge. I haven't really put on any weight but I haven't really been eating much I've been really tired and dizzy and getting fustrated really easily. I think my stomach looks a but bigger but I don't know. Can someone please help me or tell me what might be wrong I'm really scared!
