CM question No Pic (little tmi)- Please Help

KA
So I wake up this morning, walk around the house a bit and all of a sudden I feel as if I have just BD stood up and have his stuffs coming out of me (only way to explain) I was quite wet. So curious me sticks a hand down my shorts to see what's up and I have quite a lot of Watery Milky very small granulated CM, it doesn't smell. This is unusual for me, as I am generally quite dry or have sticky cm at this point in my cycle (4 or 5 dpo) Does anyone have the same when AF is near?? Or could this be a good sign??
