29 Day Cycle Overview
Ovulation: Day 15

High Fertility: Day 1016 | Next Period: Day 30

Is It Late, or Just Delayed?

If your cycle is normally strictly 29 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 34 without a period.
