Our surrogate took the following on 7 days post 5 day transfer secretly without telling me. I am glad she did it so I have a record of it. That was the day before our beta on 8 days post 5 day transfer, which yielded the result of 204.
For my satisfaction, she spent money and bought two First Response Early Response pregnancy test. This one was taken on 11 days post 5 day transfer. Beta the day before was 464.
On 20 days post 5 day transfer, she did the following. Notice that the dye of the test line pulled color from the control line.
