HCG levels rised, but progesterone levels fell

Sky08

Hi,

  I went in and got a blood test done today to make sure my numbers went up.  My HCG levels did rise from 500 something to 900 something, however my progesterone levels fell from 8.0 to 7.2.  Does this mean that I am miscarrying?  Is anybody else going or has gone through the same thing?  I am really scared that I am having another miscarriage.  Any advice is much appreciated.  Thanks.
