first appointment

Valerie • Hello babes! My name is Valerie, I`m 24 and im pregnant with my first (hubbys 2nd) with my amazing hubby Aaron (24)
Set up my first appointment today at the birthing center for March 9th! I'm excited and nervous all at the same time! Based on my lmp I will be exactly 6 weeks (they don't let me alter the ovulation date) but based on the I will be 5 weeks and 4 days. 
Any veteran mamas tell me what I could maybe expect my first visit?
