i'm sure they didn't try until i was about 15 weeks with DS (lots of padding though ). the ob couldn't find it, told me not to panic & then went into a panic herself trying to get an u/s machine to check (this was in a public hospital)...then she couldn't work out how to turn it on. thank goodness there was a midwife there i wasn't even worried till she worried and everything was fine - i rekcon it was more like 17 or 18 weeks before we heard it, but my memory is awful!

is your scan today? good luck & i hope you enjoy seeing your baby
