Do a home pregnancy test at 3 weeks after the episode of sex. . If the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the instructions carefully. If there is still concern, get a blood test for HCG. If you do not wish to be pregnant, use contraception all the time, every time. Consider implanted contraceptive, or IUD.
