I got my implanon a year ago and haven't had a period until 7 months in. It was normal and lasted one week. I've recently have had my period for 14 straight days, it started light but is now very heavy with extreme cramps. I've also been extremely fatigued and having body aches these two weeks. I've also lost about 10 pounds without changing my diet... if so I'm eating more. I'm worried because I also have endometriosis and am concerned it may be growing back. I'm waiting to hear back from my doctor but any help here would be much appreciated. Thank you.
