Odd cm before AF?

Ashley • Mommy to a sweet little man!
Sorry if TMI! And for yet another post about something haha 😂 I am wondering if any of you ladies get lots of watery discharge before your AF. I believe that I am 2 days late (and all negative hpts so far) but perhaps I am just having a strange cycle. However, I have had an increase in cm for about two weeks now (milky /watery) and noticed that today it has soaked my panty liner that I was wearing in case AF showed. Is this common for any of you ladies before AF? Thanks for your comments/ opinions!
