thanks for all replies. I have the same view regarding 'having one less stress factor'. I definately have to say something, will just have to see how it goes.

We have decided not to tell my mum (because whole family - aunts/uncles/cousins/inlaws will find out) and sister (she is super fertile so will be asking me every week whether utd). So i feel a bit strange telling work but not family. But i will just have to get over that!!

Did any of you keep it from your family when you started?
