5dpo help

rebecca🤭 • expecting our first baby July 2020🍼 And it’s a... boy💙🤰🏻

I'm 5 dpo and I done a opk this morning and it showed this result, I entered it into premom and it shows it's getting higher even though I ovulated 5 days ago? I didn't miss my peak as I got a very strong positive on my opk? Why could this be getting darker ?
