I have been on Nexplanon since 4/16/16. I've gotten worse acne, and lighter periods. I am on a 4 week period. Every time my period stops I will have sex or masturbate (non penetrative masturbation) and I will bleed. Yes I do have unprotected sex, and yes my partner and I are both std and sti free. Is this normal for me to bleed this terribly? I was on Mononessa (the pill) prior to switching. Does anyone have any similar experiences?
