AFs not made any signs

So AF is due tomorrow! But I've not had any signs for her.. last month I had aches and stomach pains like two three days before she shew up! I did a test 7dpo and that came up as negative, I posted earlier on in the month feeling out as only had sex twice in fertile week and before and after it, I'm confused as does this mean it's a good sign having no AF symptoms or is she just being lazy ?
