23 Day Cycle Overview
Ovulation: Day 9
High Fertility: Day 4 – 10 | Next Period: Day 24
Is It Late, or Just Delayed?
If your cycle is normally strictly 23 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 28 without a period.
