from my understanding, in some religions, pregnancy simply isn't discussed - so obviously it happens! i think it's entirely up to you how you go about sharing your news - and, more importantly, WHEN. we shouted from the rooftops when i was finally pg with DD - but we'd been through a lot to get there - i *think* if we were to have a natural miracle now (we won't go through IUI/IVF again) - we would keep it close for as long as possible. i don't think anyone NEEDS to know you're pregnant unless that pregnancy directly impacts them (ie - unable to work due to pg etc).

if you are pregnant and you don't want to tell people, don't. but don't hold off sharing your enjoyment for fear of what others will say either - ultimately, any child is a miracle and anyone who doesn't get that isn't worth listening to!
