TTC-general doctor visit

I've been trying to conceive for about 7 mos. no luck. I've made an appt for this week to discuss it with my doctor. What can I expect from this visit. I keep up with all my yearly physicals and have annual blood work with my primary doctor (my OBGYN also gets a copy of them) and nothing is ever a concern.  What additional things would they start testing for? Just looking to prepare myself. Thank you!
