Fertility Specialist Suggested ?’s?

Katie • TTC 5 years. miscarriage Feb 18’ DNC Dec ‘18. DNC June ‘20. 🌈🌈🌈 due Jan ‘22.

I finally got my OBGYN to send me to a fertility specialist. Made the appointment, apparently this guy is so popular I had to wait until NOVEMBER, he also has a 30+ person waiting list to get called if there are any cancellations. Anyways, for those who might have gone to one before what should I prepare for and what kind of questions would be good to ask? TIA
