Etonogestrel
"Of course, birth control affects every person differently, but I wanted to share my experience to shed some light on the possibilities of hormonal birth control. I got the implant and had it for ONE YEAR. I didn't get pregnant, which was good, but I experienced extreme "mood swings" and "depression". That's what the symptoms would be called on the websites you've been skimming, but there's not really words to describe the hell that I went through. The irony is that sex didn't really matter, because I was bleeding so often and so depressed. I waited for my cycle to even out. And it did eventually and proceeded to swing in the other direction, I hardly ever got my period. Then, back to normal, then back to bleeding all the time. I was done."
