Backup now.

Most probably, you've made those commits on a detached HEAD. May you
have checked out a remote branch, or a specific commit, before you went
about your business on or after 6th?

git reflog (or git log -g) will be able to show you the history of your
HEAD before you lost it ;)

Then you can tag those commits or 'checkout -b safehaven
nameofthetopcommit' to get a branch with those commits. Now they are
safe from being pruned during garbage collection.
