Oh and if you do not know when your period is due, the pregnancy tests instructions all state, "Take a test 19 days after the last time you had sex." The reason for 19 days is because sperm can live up to 5 days in the vagina (most women get a positive within 14 days of ovulation... 14+5=19).
Take a pregnancy test on the day your period is due. There is only a 23% chance of getting a positive 5 days before your expected period, so hold off until your period is due for a more accurate result!
