I've been on the nexplanon for a little over a year now and I am supposed to start my period in the next few days and I haven't had any signs of one or anything. I just want to see of this has happened to anyone else. It is something I'm not used too. I have always had a period on any birth control and I don't mind having one every month. I just don't know if there might be something wrong or I might be pregnant. But I besides just literally having sex last night; the last time I had sex was back in August and I had a period in September. So I'm just wanting to know if anyone else has ever experienced something like this.
