Can ovulation start day 1 after your period ends?

It is possible to ovulate on the first day after your period ends. However, it is more common to ovulate around 14 days before the start of your next period. This is because ovulation usually occurs 14 days after the first day of your last menstrual period. If you have a short menstrual cycle, you may ovulate sooner than 14 days before the start of your next period.
