Negative at first then later positive?!

Has anyone else had negatives but hours or so later a very faint positive?! I have extremely irregular periods so I don’t know if I’m really “late” or not but we tried on January 5th and 6th because that’s when glow said I had ovulated (5th). I’ve taken 3 tests so far and they all come out negative but hours later there’s a faint positive. The top two are from yesterday and the bottom is from this morning. This is the best pic I could get. I know the second looks like there’s nothing there but there definitely is. Has this happened to anyone else and you were actually pregnant?
