Etonogestrel
"I'm 23 and I've had my nexplanon in my arm for about 2 month now , took me a couple weeks to realize that this birth control definitely affects my mood. I've been crying over the littlest things , I have been very emotional and I've never experienced this kind of change due to birth control ever so it must have a lot of hormones in it to make me feel so depressed for no reason.  Also I've been breaking out on my face and spotting, I haven't bled a lot which is good and its the only reason I still have it in. Also pain in my breast and tenderness."
