Pregnancy Symptoms and Signs

Pregnancy test (usually called test pack) works by detecting levels of the hormone hCG (human chorionic gonadotropin). The amount of this hormone in the body increases, immediately after egg fertilization by sperm cells. These hormones usually begin to be found in the urine 3-5 days after fertilization, but usually not detected until 10-14 days, when the next menstrual period does not occur and the potential of new mothers aware of the possibility she was pregnant and did tests. HCG levels will be highest around the age of 2 months of pregnancy, then declined again.
