Congratulations. Hope things continue to go well. Can I ask what brand of digi you used? I thought they were less sensitive than regular line test, but that one must have been pretty sensitive to pick an HCG at 9.
I think part of it depends on how you metabolize HCG. I've seen some get a positive on a digi and get a 5 (bare minimum to be considered pregnant) on a beta the next day.
Glad things are still positive! Hopefully you get some great numbers Wednesday.
