First Fertility Dr Visit

Any tips for a first visit to a specialist when TTC?

I’ve read a bit here & there about it but I’m curious is anyone has anything from personal experience to add

My husband & I have been TTC on our own for quite some time and we are now going to see a fertility dr in approx 2 weeks. They have an analysis scheduled for my husband early that morning and a consultation with us both later that day as well as an ultrasound for me. I’m just so incredibly anxious about what’s going to happen or what they’ll tell us.
