I’ve had my implant for almost three years now, haven’t had any issues til recently ( January 2018 to be exact). I had periods every 28 days for only 3 to 4 days but now that I’m in the last year of having it they’ve been very erratic. Like have my period then a few days later have it again or right now, hasn’t shown up for over a month. My home pregnancy test was negative and I haven’t had any symptoms of my period coming. Is this normal?
