Etonogestrel
"As far as birth control goes, the Nexplanon implant was really nice and convenient! I had a pretty good sized bruise for about 3 weeks after the implant was put in, and a little bit of soreness, but that's to be expected. From then on, I didn't notice it at all!

I had some pretty bad mood swings for the first few months, and figured I just needed to be patient, but instead, it got much worse and became full blown depression. While that's not good, I am prone to depression, and the implant amplified it, but didn't cause it.

If I could give any advice, it'd just to be keep an eye on how you feel. I'm sure it'll take some adjusting, so it's okay to feel weird for a little while. But if it persists, don't wait forever to get it out. :)"
