The fertile window includes the five days leading up to ovulation and the day of ovulation itself. Sperm can survive in the female reproductive tract for up to five days, so having intercourse in the days before ovulation can lead to pregnancy. The egg, however, only lives for about 12-24 hours after being released.
How to Calculate Your Fertile Window
Several methods can help you determine your fertile window:
- Menstrual Cycle Tracking: If you have a regular menstrual cycle, you can estimate ovulation by counting back 14 days from the expected start of your next period. This is especially accurate for those with a consistent 28-day cycle.
- Basal Body Temperature (BBT) Tracking: Your BBT is your temperature when you're fully at rest. It slightly dips just before ovulation and rises slightly after ovulation. Tracking this change over several months can help you predict your fertile window.
- Cervical Mucus Monitoring: The consistency of your cervical mucus changes throughout your cycle. Leading up to ovulation, it becomes clearer, slippery, and more like egg whites. This is a sign that you are approaching your most fertile time.
- Ovulation Predictor Kits (OPKs): These kits measure the level of luteinizing hormone (LH) in your urine. A surge in LH indicates that ovulation is likely to occur within the next 24-36 hours.

- Consider Pre-Conception Checkups: Consult with your healthcare provider to address any underlying health conditions that may affect fertility.

When to Seek Professional Advice
If you've been trying to conceive for a year (or six months if you're over 35) without success, it's recommended to seek advice from a fertility specialist. They can conduct further evaluations and recommend appropriate interventions. If you think you ovulated on the 16th, consider taking a test. if-ovulated-16th-when-test.
