How do I know when I am pregnant?

Home pregnancy test. The first symptom of pregnancy is missing your period. A home pregnancy test can reliably tell you whether you are pregnant or not. The very accurate, home pregnancy tests can be found at any drug store (there are multiple brands). The home test will look for signs of beta-human Chorionic Gonadotropin (b-hcg) in your urine. B-hcg is secreted by a fertilized egg and eventually by the placenta.
