My blog doesn’t show up in WP account

I have a very old WP blog that I was thinking about starting up again. However when I logged into both of my WP accounts neither one shows my blog as connected to the account. I’m pretty sure I don’t have other accounts. Is there something I can do to fix this, or a way I can find for sure what account is being used for it?

Thanks!
