Can I get pregnant

I haven't had my period in 2 and a half weeks since my last period.  I had sex with my friend several times last night and we did the pulling out method.  Id rather not take the morning after pill and just wait to get a pregnancy test.   Do you think I have a high risk of getting pregnant?  I'm a bit concerned.  I'm trying to get reassurance from my friend and he won't answer my texts either.  What should I do?  When should I take the pregnancy test?
