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.

Quantative hcg levels are drawn to establish how the pregnancy is progressing. Since the levels can vary so much from individual to individual there is no real way to determine who will or will not carry to term. Typically levels are drawn over the course of six days first to get a baseline level with the following two providing assistance with determination of due date and or the presence of multiples. A rise in levels with a decrease may indicate a potential miscarriage but is not difinitive. A rise in levels then a decrease and then another rise may be… Read more »

I found out about 2 weeks ago that I am pregnant. Based on the time frame I should be about 6 weeks. This past Friday I went to the emergency room because I was having cramping and bleeding. The doctor ordered blood work and an ultrasound. The blood work came back and it did say that I was pregnant, but that my HcG level was only 220. Today I went to my doctor,…he did yet another ultrasound, and he was not able to find anything in my uterus. He ordered more blood work. But now I have to wait. What… Read more »

i have a question my hcg levels came back <2 to 70 im just wondering if theres a chance i could be pregnant or is it negative..

9 years 6 months ago
I just want to say don’t rely on the hcg numbers too closely. We had an ultrasound last Friday because I had been spotting for a week straight, but no heavy bleeding or cramping. The ultrasound did not show a heartbeat but only measured for about 5 weeks. They did a blood test and I returned after 48 hrs for another. They called yesterday and said the numbers increased, but not enough that they felt were viable pregnancy and we were going to schedule a D&C. Today we went in for another ultrasound to make sure before scheduling the D&C… Read more »

i have recently found out that i am pregnant again. my hcg levels have dropped slightly in 48hours. doc has said its probably a failed pregnancy. this is very dis heartning as i have alredy had 2 ectopics and 2 m/c’s! back to hospital on monday to find out whats happening!! no bleeding or cramps just brown stuff. confused.

9 years 9 months ago

I’m not a doctor but you seem right on track with the increase just slightly higher than doubling, however, t inceases this high sometimes indicate multiples acording to another site I came across earlier. Sorry I don’t remeber what site. Just look up HCG level increase maybe you will come across it. My levels are not doing as well as well as yours. Congrats.
