TMI cm and symptoms? AF due nov 5

Hi everyone! Just wanted to get some opinions.. I'm unsure when or if I ovulated and believe AF is due nov 5 but not 100% as I just had mirena IUD removed a couple months ago and havent gotten a good grasp on my cycles yet.. we are ttc #2 and made a good effort in October :) I have been experiencing minor lower ab cramps for the past week or so and lower back pain for about the same about of time.. I also (tmi) have a very damp feeling and feel as if AF has arrived constantly and have to run to the bathroom and check but all it is is creamy clear-white cm and usually in good amounts all at once.. no odor or discomfort.. got a BFN this morning and hoping it was just too early (not an early pregnancy test).. what do you guys think?
