Checking hormone levels

Hey ladies, 
So my husband and I have been trying for a little over a year now for baby number 1 with a miscarage at 5 weeks inbetween. 2 days before our first appointment and the doctor couldn't even see anything. 
My husband of course now wants us to get checked out. My question to you guys is have you gone through this? And how do you even start? Do I just go to my OB and ask for him to check my hormone levels? I mean I know I ovulate every month. My CM is always on point and the OPKs always read.
