LADIES I NEED YOUR HELP

Marianna
I was supposed to be on aunt flow last Tuesday(Nov 8) I Waited a few days to see if she would show up but didn't. Bought a pregnancy test on Friday and took it yesterday morning and it came back negative. Aunt flow hasn't showed up and I'm debating if I should take another test in a few days just to make sure. 
I need some advice as to what I should do ladies 😊💕
