Yes, the first day of your period is actually the first day of your cycle--- the day before you get your period is the last day of your cycle--------- most women ovulate smack in the middle of that---- around day 14 after the first day of their period. Once in a blue moon, women will ovulate at an off and strange time. So regardless, from now on------------ use protection!! You should do so to protect against std's anyway. good luck
It's very unlikely you're pregnant if you had sex during your period.
