23 Day Cycle Overview
Ovulation: Day 9
High Fertility: Day 4 – 10 | Next Period: Day 24
Phase Breakdown & Health
A 23-day cycle is composed of two main halves. The first is your Follicular Phase (lasting roughly 9 days). The second is your Luteal Phase, which is structurally fixed at around 14 days. If you recently stopped hormonal birth control, expect it to take 3-6 months for your natural 23-day rhythm to fully stabilize.
