I have been on nexplanon for about a year and a half almost two years. I don't get periods and if I do it's a light brown and more of spotting rather than a period. Although randomly I just got my period and it is a regular red color and seems to be heavier, still not heavy but heavier. It came with major bloating and slight cramps. Has anyone had this problem? Is it normal? How long will it last? Does this mean my birth control is running out?
