I think its very normal to worry simply because we know the odds of having something happen!! We can't avoid it, and its always in the back of our minds if we seem too "normal".

FWIW - I felt DS kicking at around 16 weeks. I didn't feel DD until around 22 weeks because my placenta was at the front.

This time around - I feel so obscenely normal that DH has to remind me that I can't do this, can't do that, can't eat such and such - because I am pregnant - cos I keep forgetting!!! I'm not showing (got too much fat on my belly hehe) and don't get morning sickness, and its too early for kicks and stuff - so yeah - I'm just cruising hoping everything is going along ok in there!!!!

I'm sure everything is fine
