I had my first doctor's appointment today.  Based  on my last period,  which is typically regular, I figured myself around 8  weeks  5 days.  The ultrasound technician measured me at only 5  weeks 6  days. How realistic is it to be hopeful that my dates are off our it was mistake and we just couldn't see the fetus?  All  we saw was the yolk sac and the cord,  no fetus  or heartbeat.  I'm going back in 4  days for another ultrasound,  but I'm not sure much will change in 4  days,  if the baby is still growing that is.  Early 6  weeks may mean no heartbeat is visible yet...  I'm afraid to walk away just as unsure as I was today.  This is my first pregnancy,  and I'm having a hard time keeping my emotions in check.  I'dlike  to  stay positive but would also like to  be realistic.
