How long does it take for a woman to form an egg after period it safe to have unprotected?

After a woman's menstrual period, it typically takes about 14 days for an egg to mature and be released during ovulation in a standard 28-day cycle. Unprotected intercourse is most likely to result in pregnancy if it occurs in the days leading up to and including ovulation. However, sperm can survive in the reproductive tract for up to five days, so it's important to consider this window when determining safe days for unprotected sex. For those with irregular cycles, tracking ovulation can be more complex.
