Pill - side effects?

Spec
Hi ladies,
I had been off the pill for quite some time, but I'm back on it to start <a href="https://glowing.com/glow-fertility-program">IVF</a> in a few weeks. 
The very first day I took it, I had my first migraine in years. 
I've now been taking it for about a week, and I never seem to wake up feeling rested dispite getting 8 hours a night. 
Could this be a side effect of the pill?
If so, it worries me how I will cope with injections!
