first IVF appointment

Lucia
Hi everyone, 
I have my first <a href="https://glowing.com/glow-fertility-program">IVF</a> appointment coming up, the information says to expect it to be 1.5 to 2 hours- any advice on what to expect? 
I've been TTC for 3 years bilateral haematosalphinges had tubal surgery but failed and problem reoccurred.
