Increasing beta doubling times

itsmevkb

At what point do betas stop doubling in 48hrs?? I had my third beta on Wednesday and it was 750.? Yesterday it was 1,417 so the doubling time is around 52 hours.? My previous betas had doubling times under 38 hours.? I know it was close to doubling and I'm probably worried about nothing but I've had two losses in a row and so I'm paranoid.? It doesn't help that I've been cramping a lot as well along with some lower back pain (which may actually be from lifting my daughter but again, I'm paranoid).

You are fine.  I remember my RE saying that as long as it was doubling 66% every two days, even from the beginning, that he is happy.  I do think that they slow down as they get higher, but I'm not sure at what level.  Still lookin' good!

Just found this on a website.

The hCG levels will usually double approximately every 48 hours [ 2 days ] for the first four weeks of pregnancy.As pregnancy progresses the doubling time increases. By 6 to 7 weeks gestation beta hCG levels may take as long as 84 hours [ 3? days ] to double.The beta hCG may take more than 48 - 72 hours [ 2 to 3 days ] to double in 15% of normal intrauterine pregnancies.I remember my doc saying by 5 weeks that he does not expect to see doubling in 48 hours b/c it slows down
