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.

    Any possible explanation why the stay think I have a very high chance of multiple pregnancy.
    PS: 4 bribries transferred.

  10. My frozen embryo transfer (2) was on 13th my 1st hcg after 14 days was 60 and after 21 days was 315 and on 23rd day was 160…..am on regular hcg injection once weekly since embryo transfer is yet any scope….plz comment

  11. I am 8dp. 5dt. Fresh transfer hcg levels were 159.8 get them redone Tuesday 7:45am had 3 eggs transferred

  12. Got levels redone Monday 11dpt now 704.4 still going to Dr tomorrow to see what they’ve went up to in just under 24 hours :)

  13. Hi,I am on 10 day after ivf transfer my hcg is <5, I am so hurting,I have been feeling menstrual pain since the transfer..my period are due anytime from now..any hope?

  14. My Hcg level started at 12 at 3 weeks then 145 then 360 amd now 916 as long as your Hcg level keep going up im told by my dr you should be fine. The problem is when they drop. Everyone is different so you will see different levels unless you are carrying twins then your HCG levels will sky rocket. Im now 5 weeks and my Hcg levels are 916. And my Dr said im good as lo g as they keep rising and not dropping.
