- Luteal Phase: If not pregnant, hormone levels drop, leading to your next period.
Apart from dates, watch for these physical signs to identify your most fertile days:
- Cervical Mucus: Look for “egg-white” consistency (clear & stretchy). For details on tracking mucus, read this guide by [Mayo Clinic].
- Body Temperature (BBT): A slight rise (0.2–0.5°C) in morning temperature confirms ovulation has occurred.

- Pro Tip: Stress can delay ovulation. Keep your mind calm during this journey by using our free [Stress Management Dashboard].

- A: The 2-3 days leading up to ovulation are your “high fertility” days. Having sex every other day during your fertile window maximizes chances.

- A: Calculators work best for regular cycles. For irregular periods, combine this tool with ovulation kits or BBT tracking.
- Q: Can my weight affect ovulation?
- A: Yes, being underweight or overweight can impact hormone levels. Check if your weight is optimal for conception with our [BMI Calculator].
- Q: When should I see a doctor?
