Levonorgestrel
"I had been on the depo since a young age due to my periods landing me in the ER each month because of vomiting. My body & depo worked well together, so I was disappointed when my gyno recommended me switch to something lighter. Skyla it was. Insertion was painful but over quickly. The after effects are what took me down. Fainting, vomiting, unreal cramping by the time I got to the car & whole first day. Nausea & cramps the next week. Now I just cramp terribly all the time. Every day. For 2 months. That being said, I am thrilled to have mine removed tomorrow. My experience will not be yours, but I do recommend hearing other stories so you can be prepared but do not fear IUDs or your insertion process! Each woman will have her own experience"
