A woman can get pregnant seven days after her period. According to Baby Center, a woman is most fertile 14 days from the first day of her period if she has a regular 28-day cycle. If a woman menstruates for seven days, she would be most fertile a week later.
Since all women are different, it's quite possible to get pregnant any time, according to New Health Guide. The site also advises that a woman is more likely to conceive during the days leading up to ovulation and less likely to get pregnant after ovulation has occurred. A woman is most fertile one day before ovulation, according to New Health Guide.
