IVF beta hCG levels calculator: scatter chart and doubling time

Beta hCG database, levels chart, scatter plot and doubling time calculator by days after ovulation, IVF embryo transfer and missed period in early pregnancy.

“Normal” doubling time

Beta-hCG LMP (DPO) * Doubling time
< 1200 < 5 weeks (21 dpo) 2-3 days (48-72 hours)
1200-6000 5-6 weeks (21-28 dpo) 3-4 days (72-96 hours)
> 6000 > 6 weeks (28 dpo) more than 4 days (96 hours)

LMP – last menstrual period.
DPO – days past ovulation (post-ovulation).

High levels of hCG

Extremely high levels of hCG may suggest multiple pregnancy (twins, triplets, or more).

Low levels of hCG

A low level of hCG may mean that ovulation occurred later than expected, if the HCG level is rising (doubling) adequately.

  4. You just gave me hope! I have been so worried and the doctor is nice but the nurse calls with results of my numbers and pretty much tells me it’s not going up fast enough and I should go to the er and get a shot because it maybe a tubal pregnancy but I’m going to wait it out until I get the ultrasound. I go again tomorrow for labs to trend my HCG. Fingers crossed
