It is possible for a girl/woman to get pregnant at any time during her menstrual cycle. Females are able to get pregnant when they are ovulating, usually about 14 days before their period and then again 10-14 days after their period. So it seems like a woman would be unable to get pregnant during her period. However, ovulations can occur at any time during their menstrual cycle. Stress, illness and other factors can bring on ovulation at various times throughout the cycle, especially for adolescents.
