Getting anxious about RE 1st visit

Alex
I am going to the RE for my first visit on Tuesday and I'm feeling really discouraged. I have PCOS and my fiancé and I have been ttc since November 2015. My obgyn hasn't been much of s help shes had me in metformin for a few weeks but all its done is make me nauseous and lose my appetite and won't give me clomid till 1 year of being unsuccessful so I'm seeing an RE but I'm worried they won't give me clomid either. I'm iust tired of every month not getting pregnant. I don't want another letdown.
