strong reaction to the mini pill

I started taking the mini pill about three weeks ago and I was fine for the first week. Then I started having stomach aches and it progressively got worse. On top of that I started to get really tired, like needing to sleep 12 hours a night. I also started getting more dizzy than usual. This morning everything came to hit me like a train, I couldn't move my head without getting dizzy, no matter how slow I moved it, I had bad nausea and ended vomiting twice including water I drank and I was sweating like crazy. I also have a light migraine on and off when my stomach hurts more. I am basically thinking of stopping taking the mini pill because I couldn't even stay at work. I can't switch to the combo pill because I have migraines and I basically started taking it because I have quite a painful cyst in the uterus and my gynecologist doesn't want to remove it. Has anyone else ever had such strong reaction or heard about someone who has? I am not sure if what I am experiencing is completely normal edit: I finally found the paper that comes with the pill and everything I am experiencing are uncommon side effects so looks like it is more or less normal :/
