First obgyn appointment

Nadine
Hi lovely ladies,
I'm 44 & hubby is 43. We've been ttc for four years now without success. 
Tomorrow morning I have an appointment with the obgyn & I wanted to ask you, what questions should I be asking her? I had my thyroid checked & that came back in the normal range. 
My periods are very irregular & have been since I came off birth control in 2012. 
Thank you in advance :)
