Can I be pregnant??

Okay so me & my boyfriend have sex pretty often & he goes in raw for a little bit (I'm not on birth control) & I did just get done ovulating yesterday morning & we had sex last night & he went in raw for quite a while before putting on a condom. & it was the second time that night & he didn't pee. But we do that pretty often. I do know that precum can only get you pregnant if they don't pee inbetween (which he didnt) & while I wasn't ovulating anymore I'm freaked out. I'm not supposed to get my period until around June 1st & the wait is killing me. I dont know if I should worry or not. So can someone tell me if I should be worried???
