Ohhohh... I might sound a little bit too advance here but I'm not really pro-teenage pregnancy so just a heads up, be acquainted to a contraceptive and the more natural it is, the better. Check out fertility monitor products like Lady-Comp or Clearublue too before it might be too late.

A lot can happen in a vacation and traveling has been proven to bring people closer so its always better to be safe than sorry. Believe me, you don't want to be another teenager asking "my period is a day late, am I pregnant" questions.

Go girl! I know you will have a great vacation!
