Just thought I would update everyone...as I always wonder what happens to the person who posted the thread...

I told my boss yesterday (so I'm now 11 1/2 weeks) and he was wonderful. He has left it to me as to whether I want to move into a slightly less "responsible" role for the time being and then when I am back from Maternity Leave, I can pick up my career where I have left off.

Such a relief! And thank you to everyone who posted replies xx
