HCG level chart and hcg levels charts at 4, 5, 6, to 12 weeks

I present here The reference intervals and normal ranges of hcg levels in a table FOR B-HCG IN PREGNANCY calculated by weeks after normal last missed menstrual period (LMP) and by days post ovulation date (dpo), I listed in this post many detailed and concise charts of the hcg beta-subunit ranges to guide every woman to know the health of his fetus and the most accurate date of gestation and birth.
All charts of hcg levels in the concentration unit mIU/mL which equal to IU/L.
The hcg level can be detected by any blood test using a chemical assay after 6 – 12 day after successful fertilization, hcg peak early in blood then exceeds by the day 8 – 12 to exist in a urine tests.

Why hcg level charts is vary in numbers?
hcg level pregnancy charts vary according every Lab and by concentration unit of beta hcg subunit.
At any hcg level chart when hCG < 5mIU/ml is considered NOT pregnant and the hCG level >= 25mIU/ml is considered pregnant, however 90 % of pregnant women have an hCG level doubles in concentration every 2-3 days (48-72 hours).
What is the best chart of hcg levels to calculate my pregnancy age?
You can choose any chart from the below ones as you knew your last missed period date and ovulation date.

How to convert hcg levels chart by weeks to hcg levels chart by days?
Most charts of human gonadotropin hormone give in gestational weeks, e.g. 3 weeks after beginning of menses = 3 weeks from last menstrual period (LMP) = 1 week after ovulation (DPO) = 1 week before period is due, in a standard 28-day cycle period.

Hcg level chart by week of Gestational Age post LMP in hCG beta subunit IU/L:
2-3 weeks the HCG level is among 10-70

The hcg level chart for twins and molar pregnancy hcg level chart
If the woman has a singleton baby the above chart will be a good indicator on the pregnancy age. To calculate beta hcg level chart for twins (multiples chart) and molar pregnancy by DPO in mIU/L of hCG beta-subunit level:
In women who are having a multiple pregnancy, twins pregnancy or more it is common for their hCG levels to be 30-50% higher than those with a singleton pregnancy. But this elevation is not evident until after the first period is missed.
A very rapid increase in hCG levels can be cause for concern but not accurate as well.

What should your hcg level be if you are 5 weeks pregnancy?
The hcg beta subunit levels at 5 weeks chart can be calculated by your own numbers as I do below:
In the hcg level chart by LMP it must be a number between 18 to 7,340 mIU/ml or IU/l
In the day post ovulation chart the 5 weeks post gestation (LMP) are equal to 35 days and if your menstrual cycle is 28 days then 5 week LMP is corresponding to the day 21 dpo, so that the hcg level in the day 21 post ovulation is a number around 1248 IU/l, if your period cycle is 30 days then the ovulation starts at the day 16 of LMP and the 5 weeks LMP must be arounf the 23 dpo and hcg level will be 2439 IU/l.
What is hcg level for a woman who is 6 weeks pregnant?
6 weeks of pregnancy means 6 weeks post gestation (LMP) and 28 days post ovulation (DPO).

25 weeks to term (third trimester)
3,640 to 117,000
My recommendation for pregnant women:
Read carefully charts data before calculate yours and rememebr your missed period date and ovulation date for better calculation.
The sonogram or U/S sonar imaging is the most sensitive method to know most baby data.
Triple test is most frequent screening tests during pregnancy period.
