Was my scan too early?

Hi Butterflies,
Thank you for your kind thoughts it's lovely to know that there are sympathetic ears out there - it's a nice feeling I've got a referral for a blood test on Monday next week to check to see if my HCG levels have increased, my Dr has explained that if the levels are up around 30000 then we will need to do another u/s to find out where the baby is (fingers crossed), but if the levels have dropped then we can safely say that I would have had a mc. He's indicated to me that he thinks that the levels won't have increased and that I shouldn't get my hopes up, but I'm still getting all of the same pregnancy signs - shouldn't these have stopped?
