A 16-year-old ambitious dancer and her boyfriend discover that she is pregnant before her important competition and have to make a decision.

That's the conflict -- what's the story? All characters have to make decisions; it's the basis of every scene they're in...at least it should be. Loglines are the protagonist, antagonist, conflict, and stakes. These are hinted at here but not defined, and not in dramatic fashion. What's the competition for? What does she stand to gain or lose, by winning or not? How does her condition affect this, will she drop out, dance with a big belly, hire a babysitter, what? There isn't enough detail here to see what the story could be. An ambitious teenage dancer discovers she's pregnant right before a big competition, and has to track down her boyfriend to tell him before showtime. If it's more about whether they opt to keep the kid, mention that. Whatever makes the stakes clear, with the main character's goal stated.
