However, some women continue to have bleeding even while pregnant. The following are the most common initial signs of pregnancy. However, each woman may experience the signs of pregnancy differently. These early signs may not positively indicate pregnancy, but may actually signal another process occurring within the body. A pregnancy test can provide more accurate results.
Pregnancy is confirmed with a pregnancy test.
A pregnancy test can be performed on either urine or blood. Levels of the HCG hormone double every two days during the first 60 days of pregnancy. Pregnancy tests that are performed using the woman's blood are done by a physician and are usually performed to obtain a very early diagnosis of pregnancy or also to confirm an at-home pregnancy test. Blood tests are almost 100 percent accurate and can detect pregnancy approximately one week after conception. Women can conduct an at-home pregnancy test by testing a sample of urine.
