CM confusion! Pregnant? Please help xo

Sky • Expecting baby boy due June 18th 💙
my AF is overdue by 3 days, I've been having usual symptoms and for the last 3 days I've had really creamy milky white CM? I constantly go to the toilet checking to see if it's AF but I just have a lot of CM?? What does this mean? Usually I'm super dry before AF pops up!! Anyone had anything similar and been pregnant? I'm hopeful but don't wanna get my hopes up till I wait to test. I always get bad cramps up until the day AF arrives but I experienced some cramps a week ago and haven't had any AF like pains since then?? So not normal. I am not under stress, I excersice regularly and live a healthy lifestyle so am hoping this increases my chances of getting BFP! Thanks :)
