What to ask? Please help!

Ashley • Married. TTC baby #1

So AF due today and nothing. No symptoms or anything! Which is weird bc I get them a week prior. I'm going to my doctor next week. 2 years ago she said I might have pcos but never diagnosed me. I'm on cycle day 50 (which is normal for me). I don't think I'm ovulating bc I've never gotten a positive test.

What should I ask for while I'm there to see if I do have pcos? I'm ttc so these long cycles make it difficult and hpt was negative today.
