? from a Aug 2012 mom (1st tri'er)

So last Friday I went in due to some pain I was having, dr did an u/s just to "take a peek" and I was 99% sure of my O date give or take like, ONE day...anyway, I was sure I was 6 wks exactly and on the u/s I was measuring 5 wks and 2 days (measured the gest sac)..We saw a gest sac and yolk sac which she said was a good sign and whether I was 5 wks 2 days or 6 wks exactly it really could just be a little too soon still. I have my next u/s tomorrow at what I think is 6 wks 6 days....praying daily and hard that we see baby and a strong HB and that development really did take place this week........just wondering if anyone here was in my boat in their 1st u/s's and later you did see your LO?! TIA!!
