Positive or negative??

Hi, I’m new here and we are on our first month of TTC. I got a slightly pos opk on the 15 of December and a very pos opk on the 16th. We tested today (the 25th). This app says I’m supposed to start my period on the 31st but I’m very irregular so who knows. I think this test is neg but if I look at it SUPER close I see a VERY faint line... what do you all think? Is it possibly pos but just too early to show up fully? Am I testing too early?
