23 Day Cycle Overview
Ovulation: Day 9

High Fertility: Day 410 | Next Period: Day 24

Your Fertile Window Explained

Because the luteal phase (post-ovulation) is almost always 14 days, a 23-day cycle means you ovulate around Day 9. Sperm can survive up to 5 days internally, meaning your highest chances of conception fall exactly between Day 4 and Day 10.
