I have had the Nexplanon implant for 4 years and I don't have problem with maintaining my weight at the time of implant but I have trouble with my period when I try to lose weight. My period will stay on nonstop when I'm trying to lose weight not heavy just a light flow. I hate it. The weight will come off but who wants to have a nonstop period soon as I quit exercising and counting calories my period stops soon after does anyone have this problem? Or others with Nexplanon?
