Starting clomid, questions I should ask doctor?

Hi everyone, we've been ttc for a year and got all of the tests done and I have low progesterone. The doctor said I didn't ovulate. We're waiting to hear about DH sperm analysis. We go in Monday to talk about everything and start clomid and possibly schedule a HSG test. I was wondering if there is anything specific I should ask the doctor when we go in if anyone else has been thru this. If there's anything someone wished they would of asked about or requested when they first started infertility treatment. Thanks and baby dust to all!!
