What if Katniss was actually pregnant during catching fire

Train

(Katniss POV)

As were on the train I'm thinking about what I'm going to say to the capitol. I'm so nervous. What will Snow say? What will the people think of me? Will I be able to get out of the games? But what about Peeta, what will they do to him? "I've decided to tell Haymitch and Effie tonight" i tell Peeta. "You can't" "but i must" Effie calls us in for dinner and i eat nervously. What will they say?? All i can do is keep eating and hope for the best.
