2nd IUI failed

Well as expected my second IUI failed. Waiting to hear back from Dr. G on what to do now.

Today is 12 days past my IUI. I go in for a blood test tomorrow but I am sure it's negative because I took a urine test and it was negative. I am not holding my breath that the blood test will come back any different. I have a few things I want to talk to the doctor about.
1. Are my tubes clear?
2. How can we increase the amount of follicles produced?
3. Are you sure I am ovulating?
4. Is there a way to tell there is an egg in the follicle produced?
There are more questions I have that I hope I can write down for when the office calls me tomorrow.
