I have had the Skyla IUD for two years now and i've never really had any symptoms out of the norm from it. Just regular crappy cramps from my cycle. I just finished my period on Saturday (9/17) and had been having extremely bad headaches, almost migraine-like, since the Wednesday before, as well as cramping. The cramps started getting worse yesterday, and tonight they're keeping me awake. I'm also extremely nauseous. This isn't normal for me whatsoever, has anyone experienced this?
