Anyone ever had negative test at night and positive with FMU?

My nipples have been sore the last two days which doesn't happen to me from my period. I also have had 4 days of a positive OPK, so I decided to test. I used afternoon urine, though, and it was clearly negative. Pictures in comments.

Anyone ever tested in the afternoon, got a BFN and then a BFP the next morning?
