Has this happened to anyone ??

I took a pregnancy test yesterday because my period is late & we were going to have some drinks with family and wanted to be sure.. it came up negative, but I honestly didn’t even wait 3 minutes bc I thought “I already know it’s going to be negative.” Well later when I was moving the trash, I noticed it was blazing positive. I know that there’s a time frame and after a certain times it’s invalid and I plan on testing again in the morning.. but I was just wondering if that’s ever happened to anyone and you were in fact pregnant?

Ive never had a test that was positive later, they have all stayed negative. Just curious!
