Levonorgestrel
"I've had this IUD since April 2017. The initial issue was bleeding for about a week but other problems in the long run for me are the mood swings, feeling deep depression, and the slight weight gain. Even after eating right & working out I wasn't able to lose any weight while having this IUD in me unlike when I didn't have it in me I could lose weight fast. I do have periods but they aren't as heavy and very irregular. For me this IUD does it's job. I haven't gotten pregnant at all while on it. It's good to get if you aren't trying to get pregnant of course but be sure to do your research in advance & review others side affects to it before getting it which I wish I did but didn't. If I did, I wouldn't have got it and I plan to remove asap"
