Pregnant!!

Okay so I really think I'm pregnant and I really don't want to be. I might not be and just be paranoid because me and my SO have sex without a condom almost on a daily but I'm not sure. I don't have the money to bye a pregnancy test and the app says that I'm 5 days late. What should I do. Wait until the end of my month to see if I get my period or get a test right away some how?!!! Please help me!!! I'm only 16.
