Pregnant?: Preganacy is always a possiblity. Purchase a home pregnancy test. These become positive at about the time youd start your next expected period. If negative, repeat in 1 week.

Very Unlikely: You were on cycle day 8 and most women ovulate between cycle 12-14. In the average 28 day cycle the egg is produced around day 14. Sperms can live happily 48 hours in the vagina or the uterus so the most fertile time is day 12 to day 16.
