Cervical position?

According to this app I am 3 days late for AF.

What should my cervical position be if AF was on her way?

What should my cervical position be if I was in early pregnancy?

I'm not 100% sure what I'm looking for but I'm almost certain my cervix is closed.

Also, how close to your AF does your cervix position change?

Could someone help with the information for me please? I really don't want to get my hopes up as I'm scared I'm not pregnant. We have been trying for baby #1 for 8 months
