Anyone off bc and suffering PCOS smyptoms?

My husband and I decided to start trying, as instructed by my doctor we could try right after I take our my Nuva ring, she started that some people are able to get pregnant in the first 2 months, and after 2 months some women have issus staying regular.
I'm just wondering what are some people experiances?Has your body stayed normal, or did the pcos come back and give issues again? I'm currently not on any medications. Before I was on the Nuva ring and 2000 a day Metformin.

I am still pre-op and i just stopped taking bc and i am going to try the shot after wls  , but i think i am going to go back on them, i have has horrible cramps since i have been off . 
and when ttc i was off bc for a month and got pregnant and there wasn't enough time really to see any side effects.
