Need help to login to my account

Hello, I have an account with worldpress and my host is Bluehost. I reset my blog because I installed many themes in it. It said “error”. Then I could not log in to my account anymore. When I tried to reset my password with my email, it said “this email is not registered”.
So, I registered with my email again and tried to login through Bluehost. However, it still said “this email is not registered.” What should I do?

Thanks.

Kelly
