Thanks everyone for your kind wishes.

Good news! I couldn't take it anymore so I told my work about the baby. They are very excited and will do everything they can to fit in with me leading up to and after the baby is born! I keep my senior position and rework my role if need be. I couldn't ask for it to be any better. I am only 5 weeks along but how I look at it is that I need the support from now and I didn't want to wait!
