Turns out Lindsay Lohan did not leave the Betty Ford Center last night ... TMZ has learned.

We've now learned Lindsay left Betty Ford at around 4:00 AM today, accompanied by medical professionals from Betty Ford ... and Dina.  Sources tell us the B.F. reps are prepared to testify that Lindsay is doing well and would be best served going back to the Center ... rather than jail.

We're told Lindsay did not leave yesterday because she wanted to show the judge how serious she is about taking the program.
