Ovulation tests - first month using

Would you call any of these positive, specifically the darker ones? This is the first month I’ve started using these test and thought I’d see what those with experience say. According to this app I should have ovulated last Thursday 4/26. 4/25 was the first darker one I got, but wasn’t sure it was positive. I’ve been reading/taking pictures after 5 minutes and they still have a little pink to them. Should I wait a little longer than the 5 minutes?

Thanks, ladies!
