Fertility doctor questions!!

Michelle TTC baby #1

Has anyone ever been to a fertility specialist?? I have an appt next Thursday and I'm so scared! My husband isn't coming with me bc he has to work, and he also doesn't like the idea of getting a semen analysis in an office!! Plus, my insurance doesn't cover ANY of this!! Ugh!! Please guys, help answer this... what do I need to expect here?? We've been TTC for 7 months now...
