Evap line?

So first of all I KNOW you should not read a pregnancy test after the time limit. I know this I have two kids. The only reason I ask this question is because my 2nd born I had read the rest after the time limit and it was positive but I thought it was just a evap line with color. So has anybody else had this happen or is this just by coincidence that I was pregnant. I had no symptoms I just tested because we had unprotected sex when I ovulated. This time it was in my fertile days. Has anyone had a pink dye evap line come up pink but was not pregnant? Please no rude answers 😕
