To check your cervix, insert a clean finger into your vagina while in a comfortable squatting position or lying on your back (many women like to check in the shower where everything is clean and lubricated by water). Make sure you use the same comfortable position each time for consistent measurements.
Your cervix is located towards the back of your vagina, but its position and texture will change during your cycle. These changes are what gives us clues about our fertility. During menstrual bleeding, the cervix is usually low, hard and slightly open to allow blood to flow out; it will feel like the tip of your nose.
After your period stops, your cervix will remain low and firm but closes up. As your cycle progresses and approaches ovulation, the cervix rises up to the top of the vagina and becomes softer and moister. At the height of ovulation, the cervix feels soft like your lips and it is ever so slightly open to allow sperm to enter in. This position, called SHOW (Soft, High, Open and Wet), is your most optimal time to get pregnant. After ovulation occurs, the cervix drops lower and becomes more firm - once again feeling like the tip of your nose. This can happen immediately after ovulation or may take several days. This cycle will repeat every month untill you become pregnant. Then, as early as 12 days after ovulation, the cervix will rise up and become soft again. But it will not feel open like it did in the SHOW position.
