What are the earliest signs of pregnancy?
Even before the telltale-missed period, your body may send out signals that you've conceived, says Shari Brasner, an OB-GYN and author of Advice From a Pregnant Obstetrician. These include breast tenderness, bigger or darker areolas, fatigue, and frequent urination. Some newly pregnant women experience light bleeding at the time their periods are due. "The fertilized egg burrows into the wall of the uterus," explains Dr. Brasner. "This can cause bleeding that women might mistake for a period."
