birth control
"I had the nexplanon for 2 years. The first year was wonderful, never got my period and everything seemed great. The second year things started to take a turn. I started to experience extreme mood swings, fatigue, depression, acne and those are just a few things. My period came back it stayed with me on and off and sometimes even stayed for a whole month. I've also gained about 20 pounds since on it. Let's  just say it's made me extremely emotional and made me think I'm a nut case. I actually just got mine removed today and hoping to regain my sanity back."
