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.

  1. Melinda,

    Your doubling rate is every 111.8 hours. That is much much slower than normal pregnancies. Most pregnancies with betas between 32 and 64 will double every 24 to 51 hours. This is for singletons….twins would be even faster.

    Having said that….I would give it a couple more days because at 13 dpo you’re right in line with the average hcg level.

  2. I had my hcg at day 14 ET was 228.day 19 was 2232.on day 23 I had bleeding with passed a big blood clot.on the same day hcg was 8800.my hcg on day 27 is 3656.I had 3 embryos transferred..do I have any chance to be still pregnant.

  4. Hi my first hcg was 205 then went to 845 then to 952 then to 1286 then it dropped to 1016 so my dr. Had me stop my progesterone n my hcg went back up to 1276 and my progesterone was 10. Now this last reading my hcg went up to 1416 n progesterone level down to 5.7 i dont understand these weird readings. I had an ultrasound 2 weeks ago n u could not see nothing. So when my level dropped to 1016 i had another ultrasound done iweek after the first one. And you could see the sac. At that time my level had wen back up so now im schedule for another one in one week from the second one. I have just been praying everyday bout 3 or 4 times a day that this b my miracle baby because i have had like 5 miscarriages already and i know my age has to do with it too.
