I've been through the same dilema,I even thought I was the only one.my periods started when I was 13 and I'd go on my periods once a year or twice and when I bleed I bleed very heavy I wear 2 pads and a tampon at a time but that lasts for an hour,I've been to doctors and some gynaes but they say I'm okay but I know I'm not cause now I cnt seem to get pregnant
