9 days late! When did you get your positive?

Question

I bought about 10 of the really cheap tests from Walmart, and when I initially take it, there's a faint positive. But as I let it dit and develop more, the line fades and comes out negative. Has this ever happened to anyone else??

I have a doctors appointment set up for Monday, which would make me 13 days late.

Also, when did you ladies get your BFP? I know some get it before their missed period, or just a couple days after.

Answer

It could be the dye running across where the line is (indent line) and you seeing it, but it doesn't stick to the line (not enough hcg) so it turns negative.
