weirdest cm EVER!!

soo I went to check my cm today to see if I could spot any blood to show my period would start soon (I'm two days late) anyways, my cm is sticky/ streatchy, creamy and watery all at the same time! what the heck is this?? I have never seen it before. also just for anyone wondering, I just bought tests today I'm waiting till morning, I don't think I'll get a positive though because (I hope I am) if I'm pregnant I believe I had late implantation. like 3-4 days before AF was due. sorry for all my rambling, anyone have this before??
