Is this as dark as it gets or darker?

We are beginning to try for baby #2. Last time I only did the ovulation strips a couple times and got pregnant - I had EWCM though. This morning I had a little bit but not much and I tested this evening with the strip. Is this as dark as it gets or am I not there yet? The app says “low” so I was surprised!

*** Edit to add. My period is 20 days late. I’m definitely not pregnant though. So I probably just skipped last one!? Idk. Very strange.
