Spotify frustration

So, I have a spotify family account. I cannot log into spotify to save my life. I clearly do not remember what credentials I used to first create the account. If I try to sign in with facebook it does not work, when I try to just login without facebook it says I have a facebook account. This is so annoying. What can I do to get on?

Well I figured out which email I used for spotify. However, when I try to sign in with facebook it does not accept the password, although the password is correct for the facebook account.
