Opk help?

Ka

I got some opks that had a few pregnancy tests with them. The packaging says read after 3 minutes...is this what I do with the opk too?

It seemed like the rest was still “pink” after 3 minutes. My first opk analysis said negative but then I took a picture of it now (10 mins or so) and it says positive. Do i read my opks at 3 mins when it’s still running and pink? Hope I make sense lol!!

This was my test after sitting about 10 mins.
