LH surge?

( Top is from today, and bottoms is yesterdays. )

Is this a positive, or close to? I know it’s supposed to be as dark, or darker butttt this is the most result I’ve gotten over the past 3-4 days.

I’m expected to ovulate in 2 days ACCORDING to the app! We had sex yesterday, does this mean we need to within 24-36 hours??? Thank you!!
