Tmi - increase in cm?

Megan

I'm not due af until another 4 days and we have been TTC for about 4 months. Normally before af is due, I have very little cm. however over past couple of days I have had creamy cm and today a lot of watery cm- like my pants feel wet! I know you shouldn't go by cm as an indicator of early pregnancy but I'm curious to know if anyone else experienced this and later found out to be pregnant? Tia X
