IVF questions

M
Hello all,
We have done our 6 rounds of failed <a href="https://glowing.com/glow-fertility-program">iui</a>. Theoretically the insurance company will cover <a href="https://glowing.com/glow-fertility-program">IVF</a>. We have an appointment next week to talk with our dr about the next steps. What questions should I ask? What do you wish you had asked about? 
Our major concern would be ending up with too many embryos. Maybe that won't be an issue, but we will be uncertain about what to do with them if we end up with extras. 
I think I can handle the injections. I've never been on birth control, so that could be weird.
Help.  Any thoughts on what I should know?
TIA
