It would be strange to me if a friend or family member didn't mention anything about their pregnancy once they got past say, 20 weeks or if it was really obvious that they were and they didn't say anything.

Are you fairly early on? Maybe you'll feel different in the coming weeks and want to shout it from the roof tops? I remember feeling pretty ordinary early on.

I know someone who was very obviously pregnant and didn't say anything to anyone because they had fairly recently lost their premmie baby and it must have been hard for her to feel positive about her new pregnancy.

But, you could always see how long you could go before telling anyone? It's really your choice
