Questions you a would ask a fertility specialist.?

I'm curious to know what you ladies have/or would ask a fertility specialist? 
In the last 5 five months I have had 2 miscarriages. I want to prepare myself for my next pregnancy, I can't endure another heart break. So I'm seeking out a endocrinologist, 
I need some assistance on what I need to ask or request for treatment. Any help or advice would be awesome. Thank you 😘
