I took a beta on Monday at 3:30 pm when I was 5 weeks and 1 day and it was 2,463. The next beta was taken Wednesday at 9:00 am at 5 weeks 3 days and it was 4,266,
I freaked out because it did not quite double. However, my doctor says this is perfectly normal and in range for a viable pregnancy. It was not a full 48 hours in between tests and we went ahead and scheduled an ultrasound for Monday July 26th. ( which cannot get here fast enough ).
After posting this on TMP I got some very re-assuring replies. Apparently betas take 48-72 hours to double AND once the number rises above 1,200 they can take up to 96 hours to double. (thank you Susan). And I believe these girls on TMP know more then most doctors. That and I went ahead and researched this for about 2 hours ;)
I am no longer worried. I have a doubling time of 52 hours and that is perfectly normal and within range. I am, after all, striving for normal here.
Also worth mentioning is that my first beta for my last pregnancy was a whopping 356. That was taken at 5 weeks 2 days so I think I'm way ahead of the game :)
The next 10 days could very well be the longest of my life !
