Late period???

samantha
Yeah so I could just be paranoid but me and my boyfriend had sex like 4 Times in the last 2 week's. One of these times we were worried that maybe the condone broke? We obviously examined it, but now I'm all paranoid. And he keeps asking if my period has come yet and it hasn't. It's late by two days. And I'm pretty scared. I'm a junior in high school... just ugh! I'm just scared. So what do you guys think? Do I have a reason to be scared? When is an appropriate time to take a pregnancy test?
