Freaking out

Okay so I have taken four test all positive, all very faint but positive. All lines showed up within three minutes, and I am still doubtful. My husband is no help btw he just thinks I'm crazy because I have just bought some FRER tests and I spend so much money on these dang things... Anyway... AF due tomorrow, no sign of her just yet, and I am hoping it stay that way! Am I the only one going crazy?
