Using cervical mucus to help predict peak fertility
Over the course of your menstrual cycle, the amount, colour, and texture of your cervical mucus (CM) will change, due to fluctuating hormone levels. The consistency of your CM can help you work out when you are at your most fertile.

Egg white cervical mucus: fertile
After your period you may notice an increase in CM which becomes wetter and more slippery after a few days. Egg white CM is the most fertile of all CM types. This stretchy mucus allows sperm to swim easily into the cervix. It looks and feels like raw egg whites and it can stretch about 5cm without breaking in the middle.

Watery cervical mucus: fertile
CM becomes wetter and more watery close to ovulation. This CM allows sperm to move rapidly into the cervix. When you have watery CM, you may feel as though you’ve leaked wee in your underwear. Watery CM is clear and drips or runs off your fingers.

Creamy cervical mucus: non-fertile
After ovulation CM is no longer wet or slippery. This creamy CM is considered non-fertile because it greatly restricts the movement of sperm. Creamy CM can be a pearly white or creamy yellow. It’s thick and feels like lotion when rubbed between your fingers.

Sticky cervical mucus: non-fertileIn the run up to your period CM becomes sticky or tacky. This is the least fertile CM. It’s thick and chunky and feels like gluey paste. It’s hard for sperm to swim through it.
