During your period, you’ll discharge menstrual blood. Once your period is over, your body may produce little to no cervical mucus for several days, or you may have cloudy-coloured, sticky cervical mucus. This is an indication that you’re not likely to conceive.
After a few days to a week, your body will begin to produce more mucus as it prepares to ovulate. During this process, your cervical mucus will begin to become clear and slippery, and will increase in volume as you enter your fertile window. This kind of mucus is created to make it easier for sperm to travel to your egg. You can expect to see this mucus growing clearer, slipperier and wetter for approximately 9 days. You are most fertile at the peak day of this process, when your cervical mucus becomes extremely slippery and clear, and can be collected and stretched between your fingers. Ovulation occurs within two days of you having your peak day of stretchy mucus.
After the peak day, your cervical mucus will become dry or cloudy and sticky. Two or more consecutive days of this sort of cervical mucus is usually a sign that you’ve passed your fertile window. Your cervical mucus will probably continue to be dry, cloudy or sticky until your period, though you may still notice wet mucus again just before your period starts.
