How Your Fertile Days Are Calculated
This calculator uses the standard fertility calculation method:
- Ovulation typically occurs 14 days before your next period (luteal phase)
- Fertile window includes the 5 days before ovulation and ovulation day itself
- Sperm can survive up to 5 days in the reproductive tract
- The egg is viable for about 12-24 hours after ovulation
For women with irregular cycles, tracking basal body temperature and cervical mucus can provide more accurate ovulation prediction.
Comprehensive Fertility Guide
Ovulation Signs
Recognizing ovulation symptoms can help you identify your fertile window:
- Cervical mucus changes - Becomes clear, stretchy (like egg white)
- Basal body temperature - Slight rise (0.5-1°F) after ovulation
- Ovulation pain (mittelschmerz) - Mild pelvic pain on one side
- Breast tenderness - Due to hormonal changes
- Increased libido - Natural biological response
- LH surge - Detected by ovulation predictor kits
Maximize Conception
Tips to improve your chances of getting pregnant:
- Have sex every other day during your fertile window
- Track your cycle for 3-6 months to identify patterns
- Use ovulation predictor kits for more accuracy
- Maintain a healthy weight (BMI 18.5-24.9)
- Reduce stress through yoga or meditation
- Avoid smoking and limit alcohol consumption
- Take prenatal vitamins with folic acid
Cycle Understanding
The menstrual cycle has three key phases:
- Follicular phase (Day 1-14): Period occurs, follicles develop
- Ovulation (Day 14): Egg is released (in 28-day cycle)
- Luteal phase (Day 15-28): Corpus luteum forms, prepares uterus
Only about 30% of women have the "textbook" 28-day cycle. Normal cycles range from 21-35 days. The luteal phase is typically consistent (12-16 days), while the follicular phase varies.
