Pregnancy testing?: If a woman is doing pregnancy tests at home, and gets one positive and one negative result, she can just do another test in a week to see if it is positive. If truly pregnant and it has been more than 3 weeks after sex, the urine test should be positive another week later, at any time of day. There is usually no reason to check a test between now and a week later. Just check a week later.
