AF is 3 days late. This morning I have a very faint BFP!!!?

Congrats! No your not crazy when I first found out I was using a digital. I told my brother before I told my husband and he said," are you sure its not wrong? you took more than one right?" I freaked out because i thought a positive was a positive "IT IS" so i went to the dollar tree and tested and i couldn't see the line so i went to walgreens and bought a $20 test that came back positive. When i looked at the dollar tree test again it was positive too! lol
