I Have Pcos And Was Given Progyluton To Help Regulate

I have pcos and was given Progyluton to help regulate my period as a teenager, unfortunately it is unavailable in my country now as I am an adult...what other birth control pill can I use as a substitute for it? I've heard of Novynette and Diane 35....are these brands safe to use and won't harm my chances of getting pregnant in the near future? Thank you.
