My Nexplannon has been great. I have only had scant periods since having it inserted. It expires in May and I have an appointment to have it replaced in April. However, recently, I have started having non-stop bleeding. It's bright red and there are lots of clots. There is no way I could be pregnant because I have not had sex in a year. I'm just wondering if this is normal for nexplannon as it wears off, or should I be worried?
