Birth control switch?!

married

I've been on Yaz for the past 3+ years and I love it, absolutely no side effects. For some reason the producer Bayer stopped shipping to my country and I'm out of packs. My period starts in 2-3 days, and was told at the pharmacy to talk to my doctor about finding another option. I am beyond frustrated. I keep reading about side effects and everything and Yaz seems to work really well for me.

Anyone switched pills? Did you have side effects? What should I expect?
