My daughter is 14 and since she started her period 2 years ago she has suffered massively, she is always in agony with her back and stomach to the point it hurts her to walk and is really heavy, I decided it was time to get onto the doctor although I really didn't want her to go on the pill just yet to see if there was an alternative. He has prescribed her Tranexamic acid, does anyone have any experience with this, she has read the leaflet and is scared to take due to the side effects. Any help much appreciated. Thank you, Katie.
