Switching from Monthly Plan to Yearly Plan

I just signed up...again -- and, I accidently signed up for the YEARLY plan. I was previously on the MONTHLY--  and want to switch back to the monthly -- but, I don't see any option to do that. 

If I cancel my plan -- and, re-subscribe to a monthly plan I saw somewhere else -- will I lose all of my clips and projects -- or, can I just sign back in with my user info?
