You don't say what kind of contrasts you specified (polynomial? some other?), or what pattern of differences among the means you were expecting. In general, contrasts are the best way to make sense of differences among multiple means, especially when there are clear theoretical predictions. As for reporting the results of contrasts, you can report them as Fs or ts, since they involve a single df in the numerator.
