Levonorgestrel
birth control
"I've had Skyla for about two months now. After insertion, I had really bad cramps (I'm pretty tolerant to pain but this was these were worst cramps ever). 

My flow hasn't really changed that much except I have spotting for about three days after I would normally stop bleeding. 

I have gotten my period twice since getting skyla, and I've had pretty bad cramps both times, as well as nausea. 

Hopefully everything will adjust soon so I don't have to be in such discomfort. But overall I think it was worth it since it is one of the best forms of birth control and I don't have to remember to take it everyday!"
