Congratulations! My beta was 49 at 11dp3dt. That was a fresh transfer too. When my RE called me to congratulate me and told me I was pregnant I was shocked. I was supirsed at their positivity. I was getting faint positives on hpt's as well. When I inquired on the lowish number they told me that it was fine and that they have seen live births with a beta of 10. I had to wait 4 torturous days for my repeat but the repeat was in in the 700's. I just had my 12 week ultrasound and the baby is measuring 2 days ahead. I have been following your story, I am happy for you.
