Ovulation Calculator 28 Day Cycle
Our ovulation calculator 28 day cycle is specifically designed for women with regular 28-day menstrual cycles. This is the most common cycle length and provides the most predictable ovulation patterns, making fertility tracking more accurate and reliable.
Understanding the 28-Day Cycle
The ovulation calculator 28 day cycle is based on the standard menstrual cycle that many women experience. Here's how the 28-day cycle works:
- Days 1-5: Menstrual period (bleeding phase)
- Days 6-13: Follicular phase (egg development)
- Day 14: Ovulation (egg release)
- Days 15-28: Luteal phase (post-ovulation)
In a 28-day cycle, ovulation typically occurs on day 14, making the ovulation calculator 28 day cycle highly accurate for women with regular cycles.
Fertile Window for 28-Day Cycles
Using our ovulation calculator 28 day cycle, your fertile window is typically:
- Most Fertile Days: Days 12-14 of your cycle
- Extended Fertile Window: Days 10-17 of your cycle
- Peak Fertility: Day 14 (ovulation day)
- Pre-Ovulation: Days 10-13 (sperm can survive up to 5 days)
- Post-Ovulation: Day 15 (egg viable for about 24 hours)
For example, if your period starts on January 1st, you would likely ovulate on January 15th, with your most fertile days being January 13th-15th.
