29 Day Cycle Overview
Ovulation: Day 15
High Fertility: Day 10 – 16 | Next Period: Day 30
Phase Breakdown & Health
A 29-day cycle is composed of two main halves. The first is your Follicular Phase (lasting roughly 15 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 29-day rhythm to fully stabilize.
