Etonogestrel
"I got it put in almost 3 years ago (my time to get it removed is November). It is very effective I've never had any type of pregnancy scare at all throughout the last 3 years. I did lose a lot of weight mostly in my boobs and butt, which was annoying but I guess better than gaining it. At first my period was very irregular I'd get it randomly for a few days then it wouldn't come back for months then I'd be on it consistently for months at a time. Now I haven't gotten one in at least 6 months. Overall, very effective and I liked it cuz it's just there you don't have to worry about taking a pill everyday or anything. I don't even feel it or notice it there, first couple days I got it it was really bruised but after that it's been fine."
