just pretend you didn't know.
as long as you aren't vomiting on your bosses desk every morning - should be ok.

i had a friend who was 7 months 'with the bread in the oven' before she knew.
so she only had 2 months to prepare for pending sproggy

Actually are you single my dear sly?

going to the doctor here - i went to a good doctor but she was in full ninja kit - how can i ask her can I have a glass of wine if I take this medicine?
she ticks the 'not married' box - so then they don't ask and you can't ask about any 'initmite issues' when seeing the gyno.
all depends if you are single.
