Does this look anything like yours? Remember, for a parallel period, the consequent phrase should begin similarly to the antecedent phrase. Notice that the antecedent phrase above ends in a half cadence. We know this because the C that ends the phrase could not appear in a tonic chord in this key, but it could be part of the dominant triad (F-A-C). Also observe that the consequent phrase should end on a note that is part of the tonic triad (preferably the root).
