Ive been on nexplanon since june 2017 and mt period is very irregular. It usually lasts 2 or 3 weeks and i don't go more than 2 weeks without bleeding or spotting. Ive been on my period for over a month now and its not heavy but it's more than spotting. I also think mt skin might be getting irritated from wearing pads constantly (I have pretty sensitive skin anyway). It doesn't look like the bleeding is slowing down at all. Should i be concerned and when should the bleeding stop?
