okay so ive been on the implant implanon for a year, the first 6 months i experienced a non stop dark brown period. it stopped and i haven't had one since, until a little over a week ago, it was random and came for 5 days than stopped, than came back than stopped and now its back. i'm worried because im anemic and i also am disgusted by blood. this is the best BC i've tried but this side effect has me uneasy and weary on sex (and i need that!!! ) so any help or advice would b great!!!
