What are pregnancy symptoms after three weeks?
Whether you have been trying to get pregnant or it happened unexpectedly, you may notice subtle or obvious changes three weeks into your pregnancy. Some women notice these right away but attribute them to something else, such as an upcoming menstrual period. At three weeks along, an early detection pregnancy test or a test done at a medical facility can provide a positive result. eMedTV explains that during the third week of pregnancy, the fertilized egg will have implanted or become attached to the uterine lining.
