Scientists have developed a smart bracelet that can not only identify the best time of the month for a woman to try for a baby, but also alert when the user gets pregnant – an advance that could make traditional home pregnancy test obsolete.Researchers conducted trials in Switzerland to identify minute physiological changes that take place when pregnancy starts.
