EWCM but negative opk? *pictures included*

So I’ve been having EWCM all day, just how it shows in the picture, but after taking several ovulation tests (the first two were at about 3:30pm and the others were just taken 15 mins ago) and they’ve gone from faint lines to barely there at all lines. I’m wondering what’s going on here. Can lh drop before a surge or is my body messing with me? :(
