What is one thing you wish you had been explicitly told by your clinic before IVF?

I have been thinking about this for a few months now. I wish the first clinic I went to had told me that even if an embryo is tested and implants, a lot of people in IVF still have miscarriages (and multiple miscarriages)more often than you think.

Edit: thank you all who have been responding! I hope newer people or anyone who didn’t know some of these things get info.
