im 14 and im a virgin and haven't done anything but I haven't had my period for almost 3 months now. the last time I had my period it was normal and ONE WEEK after it finished I stared again but it was really heavy and I had sore breasts and terrible cramps and I had cravings and mood swings etc. ever since then I haven't had my period. please can someone tell me what happening because im terrified that im going through menopause and wont have the chance to have kids when im older
