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.

  11. S. Sawant unfortunately it sounds like you are experiencing a chemical pregnancy. I went through it my last cycle, basically the embryo did implant but didn’t continue to grow into a viable pregnancy. Your hcg levels need to increase by at least 60% every two days for the pregnancy to be viable. Once it starts to decline you are on your way towards miscarrying the embryo. I’m so sorry. I know how incredibly hard it is. For everyone else- hcg levels are now a good indication of multiples, yes higher numbers can prove to be multiples however singletons can produce really high numbers as well. The only way to know if there is more than one for sure is and ultrasound.
