Got diagnosed with pcos need advise

So last week my obgyn told me i had pcos she didn’t really go into much detail about it and all she prescribed me was birth control idk if that normal because i reas about pcos and it said i wouldn’t be able to conceive or that it would be harder to conceive and that it’s not curable and i’m just very confused as to why i got prescribed birth control if i wouldn’t be able to get pregnant since pcos means you don’t ovulate?
