What do you wish you knew before starting?

Hey ladies,
My hubby and I have been TTC for 2 years now. I have mild endometriosis and had a laproscopy last year. We've had all the tests and supposedly nothing to stop us getting pregnant.
I changed jobs 3 months ago as I was working stupid hours so they thought stress might be why we weren't getting pregnant. Long story short, loving the new job and we are set to start trying again in a few months. 
We know we will have to do <a href="https://glowing.com/glow-fertility-program">IVF</a> and so we are saving up pretty hard at the moment.
Given we have this long lead time to trying again, I am researching and trying to know what I am getting myself in for 😀
So given you are all going through this at the moment, what do you wish you knew before you started?
TIA
