What does my discharge mean?

My period is a couple days late... I have been having unprotected sex with my husband. The other day he went down on me for the first time in a long time and ended up with an infection, my vagina was and kinda still is itchy. On top of that I noticed my period was a couple days late. I have been keeping track of my CM to see what's up. A couple days it was watery, then went to dry, and yesterday it was watery with white bits, and sticky; I wiped my fingers with toilet paper and the toilet paper got stuck to my fingers. And today my CM is white, watery, and stretchy! My period was suppose to be on the 24th but I am irregular but still, I've been pretty 'regular' these past couple of months. So I want to know what my CM might mean? Could it be healing from an infection? Early pregnant sign? I don't know.
