Am I out...?

I am 2 days late for my period. I took a pregnancy test this morning around 5am, and it was negative, without the faintest sign of being positive...

I have a son, hes two, when I was pregnant with him, I took a test 2 days late and it was clearly positive...

Does this mean I'm out for this month? I was really hoping this was our month....

AF shows no signs of coming, but I could be wrong. How long should I wait to test?/ Am I just waiting for AF to arrive at this point??

Who has had experience with this? Please help
