29 Day Cycle Overview
Ovulation: Day 15

High Fertility: Day 1016 | Next Period: Day 30

Your Fertile Window Explained

Because the luteal phase (post-ovulation) is almost always 14 days, a 29-day cycle means you ovulate around Day 15. Sperm can survive up to 5 days internally, meaning your highest chances of conception fall exactly between Day 10 and Day 16.
