Can't login

I can’t access my admin page.. kitayamanewport.com/wp-admin.php
with the same login info that I have been using

I am also getting the update emails to my email which I used to try to reset the password but it says that it is the wrong email

Nor does it recognize my login username that I have always been using…

I don’t know where else to go from here.

It’s a basic theme and I’m not tech savvy at all.
