Tranexamic acid
"When I was 13 my periods started to go mental, they would occur every 2 weeks and last for a week and they were so heavy I'd bleed through a deluxe night pad in an hour. I would spend school days in with the nurse either because I'd be in agony or I had just fainted. I wouldn't be able to sleep either as I'd constantly had to change my pad. My Mam eventually brought me to the doctor and because I was so young they didn't want to put me on the pill so instead she prescribed Cyklokapron . At first I had to take two 500mg tablets four times a day now I'm down to twice a day and it's great. My periods are still heavy but manageable, I'm no longer severely anemic I only get week long periods once a month. My periods no longer ruin my life."
