Last Monday my HCG level was 127. Yesterday (Monday) my HCG levels was 550. It appeared to double every 3rd day (or so). My doctor is concerned because it is not doubling every 48 hours - they say it should be around 1000 by now. Has anyone experienced low HCG levels such as this in early pregnancy, and if so, what resulted - miscarriage, normal pregnancy, etc.

Levels of hCG in pregnancy


Human Chorionic Ganadotropin (hCG) is a hormone that can be detected in the urine and blood of humans. This hormone increases during pregnancy so it is common to measure the rise in level using Home Pregnancy Tests ( or HPTs, which measure hCG levels in the urine) or a hCG Beta test (which measures hCG levels in the blood serum). The hCG Beta is much more sensitive then the Home Pregnancy Test and you can usually get a positive result much earlier with a blood test than with the HPTs.
Usually the reference values for hCG Beta are as follows:

Men: less than 5.0 mIU/ml - Normal

Women: Non -pregnant - less than 5.0 mIU/ml - Negative/normal

*Borderline - Between 5.0 to 25.0 mIU/ml (you could be pregnant)

*Positive - Higher than 25.0 mIU/ml

(*) These are values within the first week and few days after conception.
When you are pregnant the level of hCG increases and usually doubles every two to three days. It then reaches a maximum level by the second or third month of pregnancy, followed by a decrease occurring in the third trimester.

Here are typical hCG Beta values in pregnant women up to 22 days post-retrieval (DPR) or days post-ovulation (DPO).

DPR or DPO Amount of hCG in mIU/ml

10 5 - 50

12 10 - 100

14 20 - 200

16 40 - 400

18 70 - 800

20 140 - 1600

22 180 - 3200

Here are the hCG Beta values given by the number of weeks after ovulation:

after the 1st week and 2 days 5.0 to 50.0 mUI/ml

Between 1st and 2nd week 5.0 to 500.0 mUI/ml

Between 2nd and 3rd week 100.0 to 5,000.0 mUI/ml

Between 3rd and 4th week 500.0 to 10,000.0 mUI/ml

Between 4th and 5th week 1,000.0 to 50,000.0 mUI/ml

Between 5th and 6th week 10,000.0 to 100,000.0 mUI/ml

Between 6th and 8th week 15,000.0 to 200,000.0 mUI/ml

Between 8th and 12th week 10,000.0 to 100,000.0 mUI/ml

Note: The levels of hCG for pregnant women with twins or more are usually higher than the values above, which represent the typical values for just one baby.

My HCG levels and pogesterone levels were really low. My doctor just monitored my HCG level and prescribed me pogesterone twice daily. After 12 weeks, my levels were still rising but slowly. I was finally safe after 14 weeks. As long as your doctor is very attentative and monitors it, you should be fine. Now I'm 30 weeks pregnant and baby is kicking a lot. Good luck with yours.

I completely agree that slow rising HCG is not a sign of miscarriage. Mine started off really slow and then once I hit seven weeks it sky rocketed. Now at 9wk mine are at 200k. Your dr may continue to monitor them until week 9 like mine did. It's a great sign that they're going up. Good luck and congrats!!

Actually they are supposed to double every 72 hours...not 48.
Here are mine.....they were slow rising and I had a perfectly healthy baby! (dpo is days past ovulation)
11dpo - 20
15dpo - 167
17dpo - 686
20dpo - 828

They were low but my dr was not worried and I have a healthy 10mth old baby girl now!
As long as they are going up you have nothing to worry about, its not how high they get, its that they are moving up and not down! Slow rising HCG is NOT a sign of miscarriage....HCG delclining is.

Levels should double every 2-3 days. When they rise slowly it's a sign that a miscarriage will occur, but it doesn't mean for sure it will. This is because about half of early miscarriages are due to what's called a blighted ovum, which is where there is no baby, only a sac which causes HCG to rise really slowly before dropping off.
