The hCG levels grow exponentially after conception and implantation. [21] hCG levels typically peak around weeks 8-11 of pregnancy and are generally higher in the first trimester compared to the second trimester. The following is a list of serum hCG levels: LMP is the last menstrual period dated from the first day of the last menstrual period
For example, for a starting hCG level of 1,500 mIU/ml or less, the hCG of continuing, normal pregnancy will increase at least 49% in 48 hours. However, for pregnancies with a higher starting hCG, between 1,500 and 3,000 mIU/ml, the hCG should rise at least 40%; for a starting hCG greater than 3,000 mIU/ml, the hCG should increase at least 33% ...

Home pregnancy tests are urine tests, and normally detect a pregnancy 12 to 15 days after fertilization. [80] A quantitative blood test can determine approximately the date the embryo was fertilized because hCG levels double every 36 to 72 hours before 8 weeks' gestation.
The levels of hCG in the body increase rapidly in the first few weeks of pregnancy, doubling every 48–72 hours. [7] The highest level of hCG is reached in week 10 or week 11, later the levels of hCG can be used to estimate the age of the fetus and monitor the progress of the pregnancy. [6]
These are normal physiological adaptations that cause changes in behavior, the functioning of the heart, blood vessels, and blood, metabolism including increases in blood sugar levels, kidney function, posture, and breathing. During pregnancy numerous hormones and proteins are secreted that also have a broad range of effects.
Normally, the hCG level increases and peaks at the first 14 weeks of pregnancy, and no hCG is detected after the delivery of the baby. [9] The amount of hCG can also reflect the pregnancy. Less hCG is released in a single pregnancy. Similarly, more hCG is released if the mother is carrying triplets, than if she is carrying twins.
