Has anyone used the pill Yaz Flex? Would you please share your experiences with it. Good or Bad?

Hi,
I was on Yaz for 11 years until earlier this year and I have had no side effects at all, I suffer from cluster migraines and this pill made them less intense, I attempted to change to a different/cheaper brand a few years back and straight away the migraines came back worse than ever so it definitely was the right pill for me.
It made my periods shorter and much lighter and on my doctors advice I was able to cut down to only four periods a year with no breakthrough bleeds.
I am trying to get pregnant now so I don't know how long it will take for my body to regulate back to normal but my periods have come back perfectly regular within 2 months..
