AF due today! Help with cervix?! Please respond!

Courtney • Married to the love of my life and trying to conceive our one baby to complete our small yet mighty happy family. ❤️
So two days ago I was a little crampy, and my cervix was very low, hard and open, usually what it does right before my period, so I got really upset and assumed I was out.
Well earlier today, I felt it, and my cervix was so high, almost unreachable, soft and barely open with egg white CM. That is so weird for me! My cervix never just randomly goes up! Could this be a sign of pregnancy?! 
I'm tempted to test right now. Should I wait through the day to see if it shows and just test tomorrow or should I test now?! Opinions please!!!
