I had been on Cryselle or one of it's derivatives since I was 15. Just recently I switched to Sprintec because I had lost my insurance coverage and it was cheaper. It has been about two months since I switched and recently I have been having anxiety like symptoms such as, lightheadedness, falling feeling, dizziness, loss of appetite, emotional among other things. I didn't know if switching between these two could cause these symptoms or if it might be something else like Thyroid or Progesterone, or if it is just general anxiety? Any help would be great. I am kind of at a loss.
