OPK, Irregular Cycle, CM Craziness

So the first day of my last period was Sept 25th. I had about two weeks where I alternated between sticky, watery, and eggwhite CM (Oct 4-17). HPTs have been negative. I just started having EWCM again yesterday, and I just got some opk so I took one.. It's almost positive, right? I'm so confused with what my body is doing! Going to start temping tomorrow. Any thoughts/similar experiences appreciated.
