"i&#039;m 20 years old &amp; i&#039;ve had nexplanon for 2 years &amp; 7 months. i just had it removed today due to extreme heavy bleeding. i was told it was a sign that it had stopped working. i&#039;ve lost so much blood in a matter of 9 days that i passed out at work &amp; was in the hospital. i&#039;ve gained over 50lbs, my sex drive was up &amp; down, i never stopped my period they just became lighter, my mood swings were awful. i took zoloft to help with that. i had an ovarian cyst the size of a cuties orange! (which busted, but thankfully i didn&#039;t lose an ovary.) i&#039;ve had so many problems with nexplanon, but i tried to push through cause it really does prevent pregnancy.... but be prepared. it may work great for you, or it may make you completely miserable!"
