OPK confusion, advice wanted

posted to other boards and wanted to ask here too: I thought I had my LH surge yesterday around noon (the circled test) and the evening ones got lighter. This morning took the bottom two to see what I expected to be a fainter line. The dollar store one is negative but the one right above it looks positive? Is it just remnants from the actual LH surge? Am l likely to ovulate today or tomorrow? It doesn't really affect our BDing as he's only going to be home tonight (God willing the snow storm subsides) but I am trying to understand the madness that is OPKs...

Based on my symptoms and previous cycles, Glow was predicting ovulation for the 5th but when I logged the positive opk yesterday, it changed ovulation to today. And right now when I was logging, if I put in positive LH, ovulation predicted for today but if negative then ovulation was yesterday... What the heck?! Confused. Any insights are greatly appreciated! If it matters, still having very heavy EGCM and mild cramping.
