First Appointment next week! 1 year TTC, can anyone tell me what to expect?

Olivia
We are military so this appointment is just to get a referral (hopefully) to see a specialist. But once we actually do start seeing someone about our fertility issues, what can we expect? I'm sure a lot of lab work and tests, but where do they usually start and try first? I have never been worked up for this before. Any advice and/or input is appreciated!
