women do not always ovulate at a certian time. you could be pregnant. especially if you were using unprotected sex. hell you could get pregnant while your on your period but its rare. you could be pregnant but i would really doubt that
i dont think you can be pregnant. your most fertile day is 2 weeks from the 1st day of your period. however you can be fertile about 2 days before that day and two days after. so if you had sex 5 days after your period was over you should be ok. it depends on how long your periods are.
