typical HCG levels
What Do the Numbers Mean?

The problem is, once a pregnancy is confirmed, you need to know if it progressing along normally.  Keeping track of HCG numbers is one way of measuring fetal viability.  HCG is measured in milli-international units per millimeter (mIU/ml).  HCG is first detectable in the blood as early as seven or eight days after ovulation by very sensitive HCG assays.  Blood pregnancy tests will be positive (> 2 mIU/ml) by 10 or 11 days after HCG injection or LH surge, and levels vary with gestational age during pregnancy.

There is a large variation in a "normal" HCG level for any given time in pregnancy.  Caution must be used in making too much of HCG "numbers."  Ultrasound findings after five or six weeks of pregnancy are much more predictive of pregnancy outcome than are HCG levels.  You won't expect to see a gestational sac or the fetus until the HCG level reaches at least 1,200 mIU/ml.

However, a single HCG level cannot indicate a normal pregnancy.  In a normal pregnancy there is a regular increase of the HCG, so you need to see more than one value before you can better understand what's going on.  Additionally, a single value cannot always tell you how far along the pregnancy is, because of the wide range of blood HCG levels in pregnancy.  To illustrate the limitations of looking at a single measurement, here is a sample reference list for HCG levels in singleton pregnancies, based on days past ovulation (DPO):
  • At 14 DPO, avg HCG level is 48 mIU/ml, with a typical range of 17-119 mIU/ml.
  • At 15 DPO, avg HCG level is 59 mIU/ml, with a typical range of 17-147 mIU/ml.
  • At 16 DPO, avg HCG level is 95 mIU/ml, with a typical range of 33-223 mIU/ml.
  • At 17 DPO, avg HCG level is 132 mIU/ml, with a typical range of 17-429 mIU/ml.
  • At 18 DPO, avg HCG level is 292 mIU/ml, with a typical range of 70-758 mIU/ml.
  • At 19 DPO, avg HCG level is 303 mIU/ml, with a typical range of 111-514 mIU/ml.
  • At 20 DPO, avg HCG level is 522 mIU/ml, with a typical range of 135-1690 mIU/ml.
  • At 21 DPO, avg HCG level is 1061 mIU/ml, with a typical range of 324-4130 mIU/ml.
  • At 22 DPO, avg HCG level is 1287 mIU/ml, with a typical range of 185-3279 mIU/ml.
  • At 23 DPO, avg HCG level is 2034 mIU/ml, with a typical range of 506-4660 mIU/ml.
  • At 24 DPO, avg HCG level is 2637 mIU/ml, with a typical range of 540-10,000 mIU/ml.


Accordingly, the key to interpreting the true value of HCG measurements is to look at their progression.  In general, the HCG level will double every two to three days in early pregnancy.  Approximately 85 percent of normal pregnancies will have the HCG level double every 72 hours.  However, as you get further along in your pregnancy and the HCG levels get higher, the expected doubling time increases.

  • For HCG levels <1200 mIU/ml, the expected doubling time is 48-72 hours.
  • For HCG levels 1200 to 6000 mIU/ml, the expected doubling time is 72-96 hours.
  • For HCG levels >6000 mIU/ml, the expected doubling time is >96 hours.


HCG levels peak at about eight to 10 weeks of pregnancy and then decline, remaining at lower levels for the rest of the pregnancy.  Here is a sample listing of expected HCG levels based on time after conception:

  • 0-1 week: 0-50 mIU/ml
  • 1-2 weeks: 40-300 mIU/ml
  • 3-4 weeks: 500-6,000 mIU/ml
  • 1-2 months: 5,000-200,000 mIU/ml
  • 2-3 months: 10,000-100,000 mIU/ml
  • 2nd trimester: 3,000-50,000 mIU/ml
  • 3rd trimester: 1,000-50,000 mIU/ml
  • Non-pregnant females: <5.0 mIU/ml
  • Postmenopausal females: <9.5 mIU/ml

thanks buffy31
thank you  lXAnnabelleXl

For those of you who wonders on your cervical positions weather your fertile or not depending on your cervixs i found this:   figured id share it  http://www.getabelly.com/


CP          Firmness           Open/closed          Description                       Fertile

Low           Firm                   Closed             Post AF/ Ovulation CP         Non fertile

Medium     Medium          Ehh Maybe           Transitional cp                 Almost fertile

High       Super soft          OPEN!        Show(soft, high, open, wet)               Fertile!

Height (Position)

After your period and after ovulation, your cervix will be more easily reached, and as ovulation approaches it cruises upwards and is harder to reach - and for some women, they can't reach it at all!

Firmness

After your period and after ovulation, your cervix will be extremely firm and may remind you of your nose. Approaching ovulation, your cervix will be super soft - almost like touching your cheek or your lower lip.

Openness

In women who haven't had a child before, the opening of the cervix feels like a tiny dimple and is tightly closed before and after ovulation. If you've had a baby, your cervix feels more like a "smile" and doesn't necessarily close tightly, so it's important to get a feel for what is your firm, closed and low by starting soon after your period ends.

Quick pointers:

  • Begin checking CP the day after your period ends
  • Check only once per day (in the morning perhaps)
  • Wash your hands thoroughly before and after
  • Try to relax! Tensing up can make this more difficult
  • Sit (or stand) in the same position each time you check this sign
