Joanne, no worries.. I read from one the forum thread.. Can't remember when, also can't measure the nose.. Tat mama so worried.. But after she did further test, bb is fine. If didn't remember wrongly, her Gynae or dunno who say bb is too small. Each bb develops differently n they said Oscar test measurement more to AMO length.. So dunno which is the fact. But for sure, her bb is fine. Your bbs will be fine too!!!. As long as you dun have immediate family members with DS.. Muz believe u r fine too!!!! It's more to gene things.
