Another beta # question...

At barely 4 weeks, my numbers are more than doubling. They doubled every 1.6 days. What does that mean?

  • Let me clarify. I can't figure out how to edit that now that I hit post.

    I had the blood drawn on a Tuesday and a Thursday last week. The first number was 106.3 and Thursday's was 246.9.

    According to my cycle I was 3 weeks 5 days on the first draw. But according to my LNM, which is by default based on a 28 day cycle, I would have been 4 weeks 0 days. But I have longer cycles than 28 days. I won't get an ultrasound until June 3rd.

    The numbers themselves mean nothing alone. The fact that the doubling time was less than 48 hours is a good sign that the pregnancy is progressing. My betas were different than yours around the same time, which is completely normal.

    It's good that you won't get an u/s til then because right now you'd likely see nothing. Beta values 1,000-2,000+ correlate with seeing at least a gestational sac. Congrats!

  • Usually betas need to be 1200-1500 to see a sac. I always get an US at that point due to my prior ectopic. Honestly though they did a set of betas about 1 week and a half before I ruptured and those were actually normal....they are nice but don't totally rely on them.

  • Anything under 48 hours is just good news. It doesn't automatically mean twins if that's what you're thinking. The doubling time for my first two betas was 37 ish hours and there's only one baby in there.

  • I have always read that 48-36 hours was good. I haven't ever read what it means if its faster than that. So no specific reason for asking, just generalized was it still good. Thanks for everyone answering. I've never had betas run except at my last pregnancy which showed a miscarriage before it happened 6 months ago. So that's why they did betas again this time too.
