10 min mark?

I took a pregnancy test the first 3 min it showed negative. I said I would wait another minute but totally forgot until around the 10 min mark and it showed a very very faint line. I know your suppose to not read it after 10 min, but has anyone actually been pregnant in the same situation? I've used these test before but never showed a faint line after 10 minutes that's why I'm wondering. It's very hard to see it in the picture but in person you can see a very faint line.
