Understanding your menstrual cycle is key when you're trying to conceive. Knowing when you're most fertile can significantly increase your chances of getting pregnant. Your fertile window is the period each month when pregnancy is possible, typically spanning about six days.

Find My Fertile Days →What is the Fertile Window?
The fertile window includes the five days before ovulation and the day of ovulation itself. Ovulation is when your ovary releases an egg. Since sperm can survive for several days in the female reproductive tract, having intercourse during this window maximizes the chances of fertilization. Pinpointing this window is crucial for successful conception.

Other Methods for Tracking Ovulation
While our ovulation estimator offers a convenient way to calculate your fertile window, other methods can help you understand your cycle:
- Basal Body Temperature (BBT): Track your temperature each morning before getting out of bed. A slight rise in temperature often indicates ovulation.
- Cervical Mucus Monitoring: Observe changes in your cervical mucus. As you approach ovulation, it becomes clearer, more slippery, and stretchy, resembling raw egg whites.
- Ovulation Predictor Kits (OPKs): These kits measure luteinizing hormone (LH) levels in your urine. A surge in LH indicates that ovulation is likely to occur within 24-36 hours.
Combine these methods with our tool for a comprehensive approach to fertility tracking. If you're trying to understand what to do after your period and how fertile you might be, using an ovulation calculator like ours, combined with understanding your body's signals, is key.
