Will Bayern lose points? I don't think they will lose. They are currently running very successfully. There is no difference between winning a championship by 1 point and winning by 10 points. Right now Dortmund is right behind them, but Bayern Munich is a strong team to win any game they play without stress.
Bayern Munich's next match will be with the Schalke team which is currently in a bad position, so I would assume that Schalke is a very easy opponent for Bayern Munich because in the near future Bayern Munich will play at home to face a team that is not so strong. And Schalke has the potential to experience a drop in ranking if Schalke loses at home to Bayern Munich in the near future, because Bayern Munich is really aiming for victory in the race for the Bundesliga trophy this season.
