Etonogestrel
"First two months on this implant were great! No pain with insertion, normal periods (maybe one day longer total), slight breast tenderness, no noticeable change in sex drive/weight/attitude. But that's were my good review ends, sadly. 4 days after my second period I started bleeding heavily. This has lasted for 3+ weeks, and I got it removed yesterday bc I cannot deal with it anymore. Since the bleeding started I broke out, have been increasingly up then down, on the verge of tears most days, and barely feeling sexual (probably due to the fact I'm bleeding). NP at planned parenthood has said lots of women have gotten this removed because of bleeding that lasts for weeks, and that it may take me a few MORE weeks to stop."
