OK, so I'm driving myself nuts trying to figure this out, though I'm sure I already know.
Please post your results:
3 or 5 dt:
BFX at Xdpt
beta #1 at XdpXdt
beta #2 at XdpXdt
singleton or twins (or trips)
boy(s) or girl(s)?
I did 5dt for 2 boys IVF (PGD confirmed)
BFP at 9dpt
beta #1 at 9dp5dt = 86
beta #2 at 12dp5dt = 306
u/s on 1-4-10
I realize twins are typically higher numbers, but did read that boys are typically lower on average. I need to stop worrying so much, I know there is at least 1 in there (nurse today says "probability of one" HA) but they don't want to do any thing more til the 4th. I've had my heart set on twin boys for 4 1/2 years now.
