I am a 19 year old female and I?m having trouble with my menstrual cycle! I?m on the implant so I?m aware this is probably a big part in this but I?ve had the implant in my arm for 11 months now and have always only had light spotting here and there! For the last 6 weeks I?ve been having my period extremely heavy for seven days on then seven days off I?m now currently on my 3rd heavy period and I?m worried about my health! Losing so much blood cannot be that healthy can it? Is this normal?
