Advice?

the condom broke.. im 19 and in a serious relationship with the man but we are definitely not ready for kids, we're both still in school, im not working and my period just ended last week so i won't be able to test for a while since my period isn't due for another 2 and a half weeks. i basically just want to know if anyone has any advice on how to calm mine and my bf's nerves or anything else really..
