Help!!

I'm 3days late. I took a test at 2days late and got a BFN , took a test just now (3days late) and got a BFN.. I have been having light and quick cramps about 4days now. Neither test was taken with FMU.

Below is pics of both test.

Does this mean I'm out this month and not pregnant or do I just need to keep testing untill AF shows up?
