Condom broke

Okay so i was having sex with my boyfriend yesterday and the condom broke. We didnt realize for about a minute or so because we were really into it. He didnt come inside me, but there was a lot of precum. What are my chances of getting pregnant? He peed after i gave him a handjob earlier that day so im hoping that took care of everything.
Also- were 16 and have no money to pay for plan b
