Hi Coral
just popping in to ask if your doc gives you printout from BT folk? Mine does and I'm equally confused in a way about my second BT, so we're going for a 3rd.

My doc's point (this is the GP), is that the hCG range can be so vast. eg:

week 4 - lower =40 median=350 upper=2000
week 5 lower=400 m=1800 u=10000
w6 l=1600 m=8000 u=33000

for the record, my first BT was 86 taken last Thursday, 2nd BT taken last Sat so 48hrs hours later it was 170. Now I was happy with that...but GP said 'let's get another, and it'd be nice to see it in the 1000s....which brought me down a bit, but I'm trying really hard not to linger on it.

Hopefully though for you, seeing the vast ranges will alleviate some of your concern. xx
