I have had the implant for two weeks, and I got my period the day I got it. It lasted about a week(my periods are usually 3-4 days), then I stared getting brown discharge. It stopped for a couple of days and now it has started up again. I am hoping this will happen for the next two weeks and die off as my body adjusts. I haven't had the moods swings,acne, or weight gain. i have actually lost more weight since i go to the gym anyway, it's a plus.
