Etonogestrel
"I'm sixteen years old and yes it had prevented pregnancy and it makes me feel protected. I didn't experience mood swings, depression or anything emotional wise. I did gain about 10 pounds and I can't say that I'm complaining lol. Although honestly I hate it my doctor asked me to come in and get it in while I was on my period. After that i never got off my period and I got a nasty discharge. So I went back to my OBGYN and gave me some pill to "fix my period pattern" which made it worst. I took all the pills and I'm still on my period everyday and it's very heavy.I don't  recommend this I don't recommend birth control at all forget sex this is not worth it and I regret it all."
