Can a girl get pregnant after her last day of periods?

Yes, it is possible for a woman to get pregnant after her last day of her period, although the likelihood varies depending on several factors, including the length and regularity of her menstrual cycle.

Key Points:

• Ovulation Timing: Ovulation typically occurs around 14 days before the start of the next period. For women with a 28-day menstrual cycle, ovulation is likely to happen around days 12-14 after the period starts. However, for those with shorter cycles (e.g., 22 days), ovulation can occur just days after the period ends35.
• Fertile Window: The fertile window, during which conception is most likely, includes the five days leading up to ovulation and the day of ovulation itself. Sperm can survive for up to 5-7 days in the female body, so even if intercourse occurs before ovulation, pregnancy is still possible25.
• Irregular Cycles: Women with irregular menstrual cycles may ovulate at different times each month, making it harder to predict when they are most fertile. In such cases, pregnancy can occur at any time during the cycle, including shortly after the period35.
• Immediate Post-Period: While it is less common, pregnancy can occur immediately after the period, especially if the menstrual cycle is short or if ovulation happens earlier than usual3.

In summary, the chances of getting pregnant after the last day of a period depend on when ovulation occurs in relation to the menstrual cycle, but it is certainly possible, especially if the cycle is short or irregular.
