question: I have been on the birth control Kelnor 1/35 for a few years now and it has work great. Just this past month, my doctor without telling me put me on Zovia 1/35. I read that these two are similar but I am now noticing my thoughts upsetting me, over thinking, and thinking my feelings have changed for someone or something when just a week ago when I first took this new pill, I was fine. This does not feel like myself and I am becoming very overwhelmed and upset.  Do you think it is because of the switch?
