Hi, I had the Nexplanon implant done (11/07/13) and have recently begun having cramps, what appears to be old period blood (reddish brown, black brown) or some sort of discharge, and breast tenderness. My main concern is the discharge. I have been on birth control for several years (started on the pill, changed to Depo, and now the implant) and it has been several years since i ve had any sort of bleeding occur. I have no STDs now (had chlamydia at one point but it is gone now) and have only had one sexual partner since May of 2013. Should I visit my gynecologist or doctor about my concerns? Is this normal?
