My first test was 37 and two days later it was 107.
Congrats!!! I've always heard that as long as the numbers are doubling, THAT's the important thing! (During my first pregnancy, my initial numbers were really REALLY high and I was ecstatic thinking that was a good thing--and they did continue to double. Later, the doctor told me that it's not good for the initial numbers to be TOO high...and of, course, I miscarried).
I think little Evan will have a sibling by next Valetntine's Day-ish!!!
