extremely watery cm

My cm has been extremely watery the last few days, to the point with me thinking I have peed my pants or af was showing her face early. She's actually due to visit on 02/14. Can someone please help me discern if this is a symptom of PMS or pregnancy?! All of the articles I have been reading online each vary from the other. I don't want to test until af shows or doesn't show. (Praying for the latter.)
