Concerned

I am 14 years old and just recently had sex for the first time with my boyfriend.  We didn't use any condoms and I am not on birth control.  We didn't have sex for long probably a few minutes because well it hurt and he did not cum inside of me or near the time period which we had sex.  Being a person with anxiety I am concerned about the possibility of me being pregnant.  We had sex yesterday so I know it's way to early to tell.  I could really use some advice.
