White, stretchy discharge?

So I'm TTC and I have PCOS. I haven't been ovulating so I took birth control for a month to see if it would help. Yesterday I went to the bathroom and had stretchy white discharge that was kind of creamy. I know lots of people say that it looks like egg whites and clear when you're fertile but mine was just white and stretchy. I also baby danced when I saw I had the discharge. Could I get pregnant from that kind of discharge? I've been trying for over a year.
