Anyone experience the same?!

I’ve taken 3 of the new pregnosis tests today and have gotten faint second line on them all. I finished my period 29th was a bit lighter then usual but I didn’t think anything of it. I’ve been beyond dizzy for the past week even when laying down ( thought I might have been coming down with something but so far nothing) I have pcos so I have absolutely I clue when I ovulate. Has anyone gotten 3 faulty tests in one box? I don’t even know what to believe anymore.
