Managing IVF and work

Da
Hi guys
I just found out two days ago that we have to do <a href="https://glowing.com/glow-fertility-program">IVF</a> :(
My job is demanding and I have to travel usually once a week for work. 
How have others balanced work and <a href="https://glowing.com/glow-fertility-program">IVF</a>. I really don't want to have to tell my boss (whose wife is pregnant right now so he is on high alert to dr appointments etc). 
Would love some advice please
