You need the inciting incident early in the story, so usually in the exposition or rising action.
The inciting incident of Breaking Dawn happens before Breaking Dawn starts. Bella's marriage is the inciting incident. From that beginning comes all of the other things that move the plot: her pregnancy, her transformation into a vampire, etc.
During the exposition the play introduces the characters engaged in dramatic action, describing the given circumstances and defining the dramatic problem. The inciting incident initiates the plot. The plot develops during the rising action as complications and conflicts arise as a result of that inciting incident. The plot and characters develop to a turning point sometimes called the reversal or the technical climax in which the plot takes an unexpected turn. Then, the characters are thrown into a crisis during the falling action following the reversal, which leads to a resolution of the plot in the denouement, which brings about a catharsis in the audience unless it is a deus ex machina.
