28 Day Cycle Overview
Ovulation: Day 14
High Fertility: Day 9 – 15 | Next Period: Day 29
Your Fertile Window Explained
Because the luteal phase (post-ovulation) is almost always 14 days, a 28-day cycle means you ovulate around Day 14. Sperm can survive up to 5 days internally, meaning your highest chances of conception fall exactly between Day 9 and Day 15.
