Fertility Doctor on Thursday... advice?

Samantha • Mom of a beautiful 2 year old, Emmy. Trying to conceive miracle #2, TTC for a year so far with PCOS.
Hi Ladies! So after 2 failed rounds of Clomid I am going to see a fertility specialist for the first time on Thursday! What should I expect? I am nervous, anxious, excited, and very emotional about this journey. If you've been to a specialist- what did they do for you and how long did it take you to conceive?
