Well MY blood test was "are you pg" test - no #'s associated with mine - I just couldn't stand trying to figure out if the tests WERE positive or not!
I didn't get any hcg #s or any re-draws, it was just a "you're pg/you're not pg" kind of test.
I am with you on finding the heartrate with a fetoscope around that time too (I don't think I heard it until last time at 24w when I first tried - it was so cool I cried). It sounds so incredible through a fetoscope too... it's very clear (though not loud) and very warm sounding.
Except I won't be seeing anyone unless I change my mind - I do my own pg care.
So don't be influenced by us POAS'ers, no need for extra stuff, I just can't help doing it.
