Etonogestrel
"Loved that it is so hassle free. You do not have to remember to take a pill everyday or to get a shot every couple of months. It is good for 3 years. I had mine removed because I was fed up with the side effects caused by the hormones. I became EXTREMELY emotional, my hair started shedding, WEIGHT GAIN!!, always feeling sleepy, etc. I could go on. If you are ok dealing with possible side effects then I highly recommend it because everyone will react differently. I had a period twice within the year that I had it. My best friend had it and she was on her period everyday for 2 years so it just depends on your body. I switched to PARAGARD IUD. Bye bye hormones :-)"
