When is it fair to tell work that you're expecting? I want to wait until 12 weeks but (aside from the excitement of it all!) I don't know if that's fair on them. I'm an office manager (in a small firm), so it's not just like they'll be able to get someone else in the office to cover my job while I'm on maternity leave.

To make matters more complicated, another girl in the office is 15 weeks and told everyone at about 7 weeks... which makes me feel like I'm not doing the right thing by holding out for so long.

I AM still going to wait until after my 12 week ultrasound, but I'm concerned my boss will think I've been unfair by 'holding out' for so long... on the other hand, it's not like they would start to work out a replacement for me this early anyway!!

Sorry for rambling but every time I come to work I feel a bit guilty that they rely on me so much and I'll be gone in a few months!!!
