HCG table - guide to HCG levels during the different weeks

The pregnancy hormone Human Chorion Gonadotropin, also called HCG, is a hormone that the body only begins to produce when pregnant. 

HCG is formed when the fertilized egg has settled in the uterine cavity. Thereafter, the level of the hormone doubles every other day until week 20.Most people do not know the exact HCG level in the body unless you get a bloodtest that measures the amount of HCG in the body. When the level has exceeded 10 miu, an early pregnancy test will be positive. See our selection of sensitive pregnancy tests here: Tidlige Graviditetstests – Gravidtid

Difference in when HCG rises

Especiallyin early pregnancy, there can be large differences in HCG levels. This is because the body only begins to produce HCG once the fertilized egg has set, after a migration through the fallopian tube. That journey can take anywhere from a day to a week without it being abnormal. But it also means that you may find that you are shorter or longer in your pregnancy because the journey has taken shorter or longer than expected. Therefore, there are also some who can test positive on a sensitive pregnancytest very early, while others only have a positive pregnancy test up to a few days after a missed period. 

How fast does HCG rise each week?

When looking at the table below, keep in mind that the weeks of pregnancy already start on the first day of the last menstrual period. That is, you are 1 + 0 a week after the first day of the last menstrual period. The table you see here is from the National Board of Health, and to understand it correctly, remember that you enter week 3 the day after it was two weeks since you last had your period. If you have a regular cycle of 28 days, that means your egg has just been fertilized by a sperm cell. By the end of that week, most eggs will have settled, and the body has thus begun to produce HCG. In a normal cycle, you are therefore in week 4 + 0 the day on which your next period should come if you were not pregnant. 

Note that HCG often rises faster than average in twin and triplet pregnancies, while conversely, it may go a little slower if you have become pregnant using IVF treatment.
