Idk what's going on?

Idk what's going on with me lol...still no AF and the frer this morning acted weird. ..The test like came up right away but then as soon as the control line started getting really dark the positive test line disappeared? ??....so I bought 20 tests from the dollar store....did two this afternoon and nothing??? Maybe faulty tests yesterday and this morning? Weird....anyone else have this happen?
