Doctor's Appointment. What to Expect.

My husband and I are in the first month of TTC. I know it is too earlier for me to get a positive opk test due to my period just ended on the 12th. Today I decided to call a new doctor, because I am now an hour away from my previous one, not because of my negative ovulation tests, but because I had miscounted the days from the beginning of my period in April to my last period this month(I didn't have one in May). So instead of 37 days, it was actually 44 days. Also, I was on Seasonique and am approaching the two month mark of being off of the pill. When I told them what had been going on they said that it was definitely something that I needed to come in for, so I have an appointment on July 2nd. For the women who have went through this or a similar situation, what should I expect from this appointment?
