Consider testing: There is always risk of pregnancy when you have unprotected sex and not using contraceptives. Timing methods are very inaccurate and unreliable. If concern about pregnancy, consider getting tested. Also over the counter pregnancy tests may be unreliable during the early stages of pregnancy. Consider recheck in near future if negative or get a more reliable blood HCG test from your doctor/lab.

Time To Test: I am surprise you would bring this to us before a pregnancy test was done. The most common cause of a missed period in sexually active adults is pregnancy. Sperm cause pregnancy if left in the vagina on any or all of the five days leading up to ovulation. You left sperm in her vagina on a very high risk day.it is time for a pregnancy test.
