Understanding Ovulation: Timing & Fertility Window Explained
Ovulation occurs 14 days before your next period, with a 6-day fertile window. Dr. Edelstein explains tracking via LH surges and temperature, and the 15% monthly conception chance for women in their 30s.
Key Takeaways
Using Ovulation Predictor Kits to Track Fertile Days
LH surges 24 hours before ovulation; testing daily with ovulation predictor kits (OPKs) helps identify the optimal time for conception, as sperm can survive up to 5 days in the female body.
Basal Body Temperature Method for Predicting Ovulation
A slight temperature rise (0.5–1°F) after ovulation can signal fertility. While less reliable than LH testing, tracking basal body temperature helps estimate future cycles.
Understanding Pregnancy Chances and When to Consult a Specialist
Women in their 30s have a 15% monthly conception chance. See a fertility specialist after 12 months of trying (under 35), 6 months (35–39), or 3 months (40+) if conception hasn’t occurred.
