ah joeve.... my BFF didn't officially announce until 21 weeks - she was too scared she'd lose it.... you are only just 13 weeks, I was thinking of officially announcing at work at the start of term 4, so I will be 14 weeks.... (but not sure if I will last!)

for some reason I thought everyone waited until 12 weeks... but it seems that people do tell the 'important people' earlier maybe I shouldn't worry so much... I think I am just scared I will jinx it... a bit like the refusal to POAS....
