I've had my nexplanon for almost two years now. (This is my second on, after a two year break to have my son) I would usually spot on and off. Some days heavier than others, but nothing too bad. A week ago I started spotting. And now I'm having a full blown period that keeps getting heavier and heavier. Blood clots the size of the Palm of my hand. Is this normal?! It's starting to worry me and its also becoming a nuesense bc I'm used to not having periods.
