Pregnancy test addict!!!!!

Ok, I got my preg tests in the mail yesterday and I've taken 4 of them already!!! Why?! I have no idea! I'm 7 days late and am expecting to see those two lines any second now. But another bfn! My hubby says he's gonna lock them up and he will let me have one per week until my period shows then if it does I don't get then until I'm one day late for my next. I'm almost tempted to let him!  Anyone else an addict?!
