The Woman During Pregnancy：The Signs of Pregnancy   

Reliable Signs of Pregnancy
There are three truly reliable signs of pregnancy: 1. the heartbeat of the fetus, which the doctor can hear through his stethoscope at about the beginning of the fifth month, 2. the active movement of the fetus, which can be felt at about the same time, and 3, the fetus becoming visible on the screen in an ultrasound examination. (There is a similar fourth possiblity: The skeleton of the fetus appearing in an X ray picture. However, the exposure of fetuses to X rays is usually avoided for medical reasons.)
