Understanding your fertile window is crucial when trying to conceive. This period, typically spanning about six days each cycle, represents the time when pregnancy is possible. The most fertile days are usually the day of ovulation and the five days leading up to it. This is because sperm can survive in the female reproductive tract for up to five days, waiting for an egg to be released.

Several methods can help you calculate your fertile window period:

For example, if you have a 28-day cycle, ovulation usually happens around day 14. Learn more about calculating your cycle at calculate cycle length.
- Basal Body Temperature (BBT) Tracking: Your BBT slightly increases after ovulation. By tracking your temperature each morning before getting out of bed, you can identify this rise and pinpoint ovulation.
- Cervical Mucus Monitoring: The consistency of your cervical mucus changes throughout your cycle. Leading up to ovulation, it becomes clear, slippery, and stretchy, resembling egg whites.
- Ovulation Predictor Kits (OPKs): These kits detect the surge in luteinizing hormone (LH) that occurs before ovulation. A positive result indicates that ovulation is likely to occur within the next 12-36 hours.

- Irregular Cycles: If your menstrual cycles are irregular, the calendar method may be less reliable.
- Stress and Illness: Stress, illness, and travel can temporarily disrupt your cycle and affect ovulation.
- Medications: Certain medications can interfere with ovulation.
