25 Day Cycle Overview
Ovulation: Day 11

High Fertility: Day 612 | Next Period: Day 26

Is It Late, or Just Delayed?

If your cycle is normally strictly 25 days, a variation of 1-3 days is still medically considered normal due to stress, travel, or minor illnesses affecting the exact release of your egg (delayed ovulation). It is officially considered "late" once you pass Day 30 without a period.
