Reproductive Endocrinologist

Hi! I have been working with my OBGYN for infertility and am on month 4 of Clomid. I ovulate day 20-23 of my cycle and have had 2 chemical pregnancies. I have finally made an appointment with an RE for July 22. I have had an HSG and my husband had a sperm analysis, both normal. My question is, will she have us do testing again? And how soon after I see her will we start treatment? I know everyone is different, but I am curious what everyone else's experience was like.

Thank you!
