Fertility Expense Advice Needed

My husband and I are two teachers from Texas and have BCBSTX insurance which covers absolutely nothing for IVF, so we have to pay for everything out of pocket. I am going to be starting stimulation some time next week, so we need to make a decision pretty quickly about how we want to go about paying for this. Does anybody have any good advice or tips on what the smartest way to go about paying for IVF is in this situation? Thank you for any sort of help!
