Getting frustrated with Mirena

Be
I switched to Mirena around a month ago because I get migraines with aura. Since I have migraines I'm at risk for a stroke. 
I've had very few side effects and now I'm noticing a few things 
1. Ovarian cysts. 
2. Still getting migraines. 
3. Dry as the Sahara desert down there. 
My boyfriend was actually in the mood for sex last night and I couldn't even get it in and I felt so stupid. Like a failure. He was nice about it and said we could get lube but I feel so bad. 
Edit- October 19: the dryness has gone away. I still get migraines and the occasional cyst.
