Is a consisting amount of CM a sign of pregnancy?

Johanna • 27 y/o RN. Engaged since 18 dec 2013 and ttc:ing (on and off due to previous work) since April 2014.

Expecting my period in a few days. Normally my CM amount decreases and eventually "vanishes" a few days before expected period. This time around that haven't occurred (yet at least 🙇🏼‍♀️) and since I know you "keep" your CM during pregnancy I was wondering if anyone has noticed this as an early pregnancy sign? ❤ #desperateforanysign
