Etonogestrel
"I've had Nexplanon since late October of 2012. At first it seemed great the not having to worry about taking a pill everyday at the same time. Mainly that's the reason why I choose Nexplanon in the first place, But over the many months now I've experience lots of Negative things about it in my perspective. 1) Huge weight Gain Like 20-30Lbs 2) Lots of headaches. 3) X2 the Acne 4) More stress 5) My emotions are much more sensitive than they ever were. I cry a lot more now; sometime I have no idea as to why I'm even crying in the first place. Just to much estrogen to handle after being in my arm for so long now. 6) My periods are very irregular now. Sometimes I'll spot, sometimes I'll bleed for just a day."
