Infertility questions from Doctor...

Becca • Newly pregnant through IVF, after TTC for two years.
33 TTC #1. Going to doc for the first time to talk about infertility. They will ask a lot of questions I hear. 
How important is it for me to know my family history? I do not want to talk with my mom about it. Is it enough to know she had 2 kids at 33 & 35 and a hysterectomy?
