Pregnancy test

HCG levels rise rapidly during the first trimester of pregnancy and then slightly decline.

HCG levels should rise every 48 hours in the beginning of a pregnancy. HCG levels that do not rise appropriately may indicate a problem with your pregnancy. Some problems associated with an abnormally rising HCG level include miscarriage and ectopic (tubal) pregnancy.

Extremely high levels of HCG may suggest a molar pregnancy or more than one fetus -- for example, twins.

Your health care provider will understand the significance of your HCG levels, and he or she should discuss the levels with you.
