skyla device

has anyone been out on the skyla? my gyno said it’s like the mirena but smaller since i’ve not had kids. i’m getting it put in next monday and was curious if anyone has used it and what some of the side effects you’ve had personally. I was on the depo 2 years ago and gained nearly 75 pounds went off birth control because I wasn’t sexually active and then about 6 months ago I decided to get put on the pill since my boyfriend and I got sexually active. I kept forgetting to take my pills and I decided an implant or IUD is the route to go since i don’t plan on wanting kids till i’m out of college. any feedback is appreciated :-)
