Are you sure they were testing HCG? I am in 2WW also & have to go tomorrow for estrogen/progesterone check. Maybe that is what your RE was checking.
10 days doc said anything under 5 not pregnant any thing over pregnant they said ideally they 'd like to see hcg at 8 and cant say if i am or not im to wait another wk to be tested again . confussed
How many days since your transfer? My levels were 399 @13 days after my transfer, and I think it needs to be at least 10 for you to be considered pregnant.
