I might be pregnant

I had sex about 9 days ago and i was supposed to start my period 3 days ago. Me and my boyfriend never use condoms and i’m not on birth control but i trust him to pull out. We’ve been having sex for almost a year now and nothing has happened. My period is never late so i’m so scared i might be pregnant. I talked to him about it and he’s really scared i’m pregnant but i kept asking is he pulled out and he swore he did. I don’t know if i believe him because if he did pull out he wouldn’t be as worried as he is. I’m getting a test today but i’m so scared i’m pregnant. I’m not ready for a baby :(
