Questions to ask at OB appointments

Hailey • I'm 25 years old and live in Northern California, I also have a 2 year old little girl 💖
What are some good questions to ask ask my first OB appointment? Or things I should be told? 
This will be my first OB appointment at 12weeks, but I will also only be seeing this office once because my new insurance will be starting after that... So I just want to ask questions that are relative to the fact that I won't be returning to this office in the future. 
Also, what should I except at this first appointment? What will they be doing?
