Understanding Your Cycle

Fertile Window spans 5 days before ovulation to 1 day after, when pregnancy is possible.
Most Fertile days are the 2-3 days before and including ovulation day.
Tips for Tracking
- • Track several cycles to determine your average cycle length
- • Basal body temperature rises slightly after ovulation
- • Cervical mucus becomes clear and stretchy near ovulation
- • Ovulation predictor kits can confirm your fertile window
- • Stress and illness can affect ovulation timing
