I had sex on last day of my period. could u be pregnant now? when would result show on hpt

Possible: Generally after ovulation, at mid-cycle, the egg only is fertilize-able for 24-36 hours. Sperm, on the other hand, generally are viable for 3-4 days in the reproductive tract but can live for up to 10 days. Therefore, if you made love on day 5-7 of your cycle, you ovulate around day 14, then it is possible that you could get pregnant. If you are late on your next period, do a pregnancy test.
