Yes, it is possible to get pregnant right after your period, although it depends on factors like the length of your menstrual cycle and when you ovulate. If you have a shorter or irregular cycle, your fertile window might overlap with the end of your period, increasing the chances of pregnancy. Sperm can survive inside the female reproductive system for up to 5-7 days, so if ovulation occurs soon after your period, having unprotected sex immediately after or during your period can lead to pregnancy.
For example, in an average 28-day cycle, ovulation occurs around day 14, and the fertile window includes the five days before ovulation. If your cycle is shorter than average, ovulation can happen earlier, making it possible to conceive right after your period. Conversely, it is less likely—but still possible—to get pregnant on the last day of your period.
Therefore, if trying to avoid pregnancy, contraception should be used even during or just after the period. If trying to conceive, the days soon after your period can be fertile, especially if ovulation happens early in your cycle.
