Those who have done IVF...

I want to make IVF milestone cards and add them to my Etsy shop. I have not gone through IVF yet (possibly the next step for us) so I don't know what milestones people would want/need.

I have looked online to see what everyone else includes, but I want to hear from you all. The sets I see online vary too.

I am keeping this anonymous and in no way advertising. I am just looking to get an idea of what all I should include.
