A.F.
I tried Yaz for 6 months, and all that I have to say is that it's horrible. It gave me intense blinding migraines, and when while it says it's supposed to help with PMDD, it made mine worse. My period were great, but the pain from the migraines and being laid out on the couch wanting to die was not worth the pain free light periods. It effects everyone differently, but I have honestly not heard anyone having a good experience with Yaz. Talk to your doc and switch.
