i m 15, 4 11 weight is 90 lbs. i ve had my menstrual cycle for 5 years now, and this is the first time i ve ever had this happen, i m currently on it but there s no blood on my pads, only when I wipe myself, I m not sure if that is a problem or if it s normal, usually my menstrual cycle is a heavy flow , so this is really unusual for me
