Okay so recently I was on The Nexplanon implant for a year ... No period ... I recently got off September 11 had a 10 day period in October && no period in November && now I’m on day 13 of my period ... should I go to the doctor ... I was cramping very bad the last week but they just stopped ... sometimes I stop bleeding for a minute and it comes back... is this normal for the simple fact I haven’t had a period in a year?
