What is going on?! Has O come and gone or am I still in with a chance?

Hi Ladies, I have been using opk's and faint lines last fee days but no strong noticeable ones. Have been charting bbt and noticed the drop in temp yesterday morning and today it has gone back up. Tested opk again and faint again! EWCM today as well. Am I due to O, have I missed it it what is happening?! Glow says tomorrow is now my highest % day and yesterday it said today was! So confused please help!
