Infertility Specialist, what was your experience?

My SO and I have decided to see a infertility specialist as I've had multiple miscarriages. I'm really nervous. It's a very different route and huge step for me. I was wondering if everyone could share their experiences with one. What was it like? I'm calling to speak with someone and schedule an appointment today. Was it helpful? Did you find out why you couldn't get pregnant or stay pregnant? Are you pregnant now? How long have you been seeing one/how long did it take get pregnant after going to them?
