Trying to decide if this is POS OPK! Need to chart accurately! Don't want to miss my surge!

Posting again, as my phone auto correct made typos and didn't make sense! Been TTC for almost a year. Started temping and opk/CM/CP testing the last few cycles.

I am able to determine my O based on EWCM, and CP, but... still NEVER have had a stark POS opk. 2 cycles ago, BFP hpt ended in chemical pregnancy. This cycle, I started testing everything earlier, ad last cycle I was 5 days late. Figured I'd give it a try more often. And.. got almost pos today at lunch. This is my PM test. One shows what I believe is pos, other (strip) does not. Which one should I go off of for charting a POS?
