Pregnant or no period this month?

Last month I got my period in Aug 1-5. My cycle is 34 days. And I was suppose to get my period September 4th and it's the 14th and still nothing. I have just been a little tired, but im kinda tired very often normally cus I'm always doing stuff. So I don't know if I could be pregnant or not? I'm 10 days late on my period. Have had sex with condoms. And without. When without he normally finishes outside of my butt. I'm going crazy. Idk.
