Pregnant?! 😍

Can one day make a difference in a pregnancy test?! I took one Saturday, because it followed the timeline from when we had sex last and it was negative. Now, it's basically Tuesday which makes me two days late for my period. Am I wasting money to take the other one now? Should I wait? I don't want to get excited until it's positive but I'm freaking out in anticipation. I don't think I'll sleep otherwise.Β
