Cervix question?

Samantha • I have an amazing husband we have been together 7 years we have a beautiful little girl who will be 5 in April! We have been ttc since November 2014. I'm a dog groomer 😇😉😍👪💖
AF is supposed to be here tomorrow, from what glow says. I've been having negative pregnancy tests but haven't tested today because I have been extremely moody and tired and thought it was pretty much going to show. Anyways my cervix is really high, like I could barely touch it. I'm on cd 28 and dpo 13. Is that normal? Shouldn't it be low if I'm about to start?
