Its Week 2 and you're just dying to find out: Am I pregnant or not? Unfortunately, you'll need to stick it out a bit longer. About four days after your egg is fertilized, it begins producing a hormone called human chorionic gonadotropin (HCG), which pregnancy tests can detect in about another week -- first in your blood (via a test at your doctor's office) and then in your urine (which an at-home screening would spot).
