Etonogestrel
"I've been on Nexplanon for about 2 and a half years. I have had nothing but problems with this thing. I have uncontrollable mood swings. Which isn't me at all. I get angry over the smallest things. I've had more UTI's which were unknown to me before being on this. I overall would not recommend this to anyone unless you can deal with extreme mood swings and other health related issues."
