What does this mean??

I have the cheap tests. At the 3-5 minute mark there is the faintest line that I can’t seem to get on camera, at the 7-10 minutes I can get it on camera(kinda) but after the 10 minutes it just gets darker and darker.. period was due yesterday.. but I think I ovulate late because I always get the egg white later on in my cycle. Like a week before my period, and my previous pregnancy always measure about a week behind, not sure exactly though because I don’t test it. Opinions please? The last picture is at like 15 minutes roughly? No later.
