HCG Levels in Pregnancy

Whether it is their first pregnancy, or they have been pregnant before, many women have heard the term “hCG” while they are either trying to conceive, or shortly after they conceive, but they don’t necessarily know what it means.

In the medical world, hCG is short for Human chorionic gonadotropin which is a hormone that a woman makes when she is pregnant. It can be detected in a urine sample or a blood sample as early as 10 days before your period should start. However, it can take until several days after you miss your period for these levels to be high enough that they can be detected.

The hCG hormone helps sustain a woman’s pregnancy until the second trimester when the placenta starts functioning fully and takes over. It also helps create the testes, secretes estrogen, and helps develop the placenta.

For women who have faced infertility issues, or who have had problems with miscarriages, doctors will routinely draw blood to check the hCG levels 2-3 times a week in early pregnancy. This is because hCG is supposed to at least double in a 48 hour period until it reaches a certain level, when it starts to decline. If the levels are doubling, it is often a sign that the pregnancy is viable and progressing as normal. If there is only a small rise in the number, no rise in the number, or a drop, it can be the first sign to a doctor or midwife that this pregnancy may not last through the first trimester.

There is no “norm” in the range for hCG levels in a pregnancy. They generally fall into this range.

Week since last menstrual period began Amount of hCG in mIU/ml
3 5 – 50 (less than 5 means you are not pregnant)
5 19 – 7,340
7-8 7,650 – 229,000

If hCG levels are taken and they not only double, but triple, quadruple or more, this is often a sign that there is more than one baby in the uterus. When a woman is pregnant with multiples, her hormones will rise much faster than they do when it is just a single pregnancy.

If you have questions about your hCG levels, be sure to ask your doctor or midwife. They are the only ones who can correctly test, judge, and give you answers regarding the health of your pregnancy.

I’m looking for some guidance. Last week I did two pregnancy tests at home, the first one was a faint line and then when I went to the doctors their urine test was negative, I was sent for a blood test but anxious waiting I took another urine test at home which was positive and the line appeared darker. My bloods came back positive but with a score of 36. My last period was on the 7th of June and still no bleeding either.

Hi ladies,
Just got my HCG results back so first ones were 130 then dropped to 94 and today results are still 94! I’ve been having bleeding like a period and had quite bad cramps last night. Has anyone’s levels stayed the same? The midwife said its very unheard of to have the same reults twice. I’m so confused

3 years 1 month ago

Last period was 13/5.

Blood work done on Sunday 12/6, HCG read 19. Blood test done again on 14/6, got results today and they read <5.. What does this mean? Dr said to retest in a week but this would suggest I'm not pregnant wouldn't it? Interested to hear people's thoughts.

I got a blood pregnancy test. Under flags it said HI, under results it said 14040 and under references it said <5. Can anyone tell me what this means? I would appreciate any answers.

Hello I had some light bleeding at what I thought 11 weeks pregnant. It then went heavier over night so got booked in for an emergency early scan at hospital, they couldn’t see anything on the scan other than pregnancy tissue or blood clots. Which I’m guessing I miscarried a while before. My blood test level come back at 1859 then dropped every 48h I went back. I got discharged 3 weeks ago today and my pregnancy tests are coming up positive still? Are they suppose to be now? very concerned and worried. X

3 years 2 months ago

I too found out last week I was pregnant 2 days after a missed period, then I started bleeding for 5 days like a period and that was it. I had cramps, my bleeding wasn’t as heavy as normal and no clots. They believe it’s a miscarrige and ectopic because hcg levels keep rising. I’m not having any symptoms. This is frustrating.

Good day. I had my first beta hcg on Feb 01 2016 it was 6303 two days later it was 8500. I have been spotting off and on for a week and based on my ovulation dates I am 21 days. I had an ultrasound last week and nothing was seen so the Dr suspected an eptopic pregnancy that’s when he sent me for the hcg tests. I am lost as to what is going on. Help

Hi I am in a similar situation and hoping you ladies can help me out. I had a period on 12/11/15 and started tested positive on 1/2/16 after taking every test there is up to 1/7/16. On 1/6/16 I went for a blood test which showed my hcg levels to be at 65. I went back today for a second blood test and I showed my levels are down to 23. Is it possible it dropped due to me not having a missed period yet or am I at risk for a miscarriage? Please help I am so confused. Thanks… Read more »

Hi wanted to know if anyone could help me with this.
I am currently 3 days late on my period which is very rare as my period is always on time. I went to get blood work done and I recieved a hug level of <^5. Could anyone tell me what this means as I know less then 5 is indicated as not pregnant. Should I get a mother blood test done in a few days?

I’m so confused. I should be about 4 weeks or less pregnant. My hcg levels on November 1st were 7.5. I have bled and now am almost completely done. Still bleeding and spotting here and there. I had another blood test done on November 3rd, and the results were 8.4 ……????? I’m supposed to go back for another blood test. I thought I had a miscarriage. If I did, WHY are my levels slowly creeping up? If someone could answer this I would be so grateful!! Thanks!

3 years 8 months ago

I had a miscarriage 4 months ago. Needed a d&c as it didn’t leave by itself. Ive had one period and now i think I’m about 7 weeks pregnant again. Its very stressful after having a miscarriage recently and now im already seeming to have doubts again. Hcg level was 6000 then 6500 4 days later. Apparently the hcg levels should have risen more than that. Waiting to do another blood test in 2 days. Hoping the levels have doubled. Im not getting attached to this pregnancy that’s all I know right now.

the hcg levels are supposed to double every 48 hours. If they are dropping or not doubling, that is not a good indication. I am 6 weeks along now and still worried about the first trimester. I had a miscarriage three months ago, had to do D&C and after one cycle I got pregnant again.

Hi. I’m hoping what I say can help anyone who needs some answers. I am an ivf patient so I’m familiar with the hcg numbers. After embryo transfer, on day 10 they check for the hcg hormone, and check every couple days via bloodwork to make sure the hormone is doubling. I am almost 12 weeks along and have bloodwork done every week and that’s a relief because I know what’s happening. If you get anything higher than 5, you are pregnant. If your numbers rise but then start dropping that means the pregnancy is most likely going to end.… Read more »

also based on my research and based on the first day of my last period my hcg levels are high even though they are moving very low bc as of today i should be 4 weeks and 5 days with levels of 4700ish if i am having more than one baby is it possible to still move slowly and not see anything in the ultrasound or is it possible that i was having more than one baby and one or more miscarried and one is still alive? just a thought
