Help? Am I pregnant

Keni

So I’m a week late today I spotted 8 days ago one at before I was supposed to start AF, I took a dollar HPT (home pregnancy test) the day after the spotting on the day of my expected period arrival but I got a BFN. My symptoms are not bad, barely noticeable. I’ve had some mild lower back cramping pain, some constipation, been a bit moody, have very had fatigue I’m always tired lol and of course no AF! Is it time to test again? I’m a week late I’ve never been this late! I’m 22 my birthday is 2 weeks away so hoping and praying for my little blessing and my BFP (big fat positive (pregnancy test)) ! Should I test today again or wait til Friday?
