Hi, i thought i would say what i did
I actually told my bosses about ttc because most of my appointments were at the hospital when i should be working so i felt it was best to be honest with them. Which they all respected me and understood why i needed to go to the appointments.
You don't have to tell your bosses as it really isn't any of their business, but i chose the other option. I am just too honest about things!!!!
Hope this has helped.
