Levonorgestrel
"I got the Skyla TODAY. I am 21. I had my first pap in March. This is the first time I've "taken" birth control. I chose the skyla because it's smaller than the mirena & lasts for 3 years. I didn't want a 5 year one because I feel like having something in there for 5 years is more gross than 3 years. It was inserted about 2 hours ago. As of now, I am feeling cramps. Just like regular period cramps. When it was inserted, it didn't feel much different than a pap. I did feel a few cramps, which were pretty bearable. My legs started shaking during the process, but I think it's because I almost let my nerves get the best of me. My doctor explained the whole process before doing anything, which was good. I would recommend this product!"
