Tests are accurate: There is no question posted but merely a statement. That said, today's pregnancy tests are very accurate and not affected by foods, herbs, common illnesses, sexually transmitted diseases, vaginal spotting, or medications. A blood test gives a reliable result 2 weeks after sex (2 weeks after when conception might have happened), or just after missing a period.
