Pregnancy unlikely: If nobody put semen (has sperm in it) inside the vagina, pregnancy doesn't happen. A home urine pregnancy test gives a reliable result by 3 weeks after sex (3 weeks after when conception might have occurred), 1 week after missing a period, or 1 week after starting a "weird" period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon.
