Cervical Discharge Through the Menstrual Cycle
Your cervical discharge changes its quality and quantity throughout your menstrual cycle.
Right after your period is the driest time - the cervical discharge is barely present. Thereafter, the cervical mucus starts increasing in quantity up to the time before ovulation, as the amount of oestrogen your body is producing increases. Around the time of ovulation the discharge becomes stretcher and looks like “raw egg whites”.
After ovulation and up to the time you get your period, the cervical discharge becomes thicker and sticky. This is due to an increase in progesterone, which also causes the lining of your uterus to build up in anticipation of a fertilised egg implanting.
If you’re using ovulation test strips, the best time to test for ovulation is when your cervical discharge begins to get thinner and stretchier, like egg whites.
