For people with an average 28-day menstrual cycle, ovulation occurs around day 14.
After unprotected sex, sperm can survive for about three to five days.
On average, people usually ovulate about seven days after their period ends.
One study of 5,830 people who menstruate examined the odds of becoming pregnant at different times of the month.
