is there any chance of pregnancy ?

i’m very paranoid right now , me and my boyfriend had sex on monday. with a condom on it was my second time doing it and he didn’t finish he said he didn’t and the condom was flat i’m assuming if he finished it would have some cum in the bottom of the condom or it would be filled up but it was flat and had nothing in it he said there was pre cum on the condom but that it never slipped off and that it fit him good and he showed me the right way to put it on and everything it rolled on easily when he put it on his dick is there any chance i could get pregnant?!! here is the condom we used he filled it up with water just to check and there were no leaks and i also checked it that same day and right when we were done he showed me that there were no leaks and only pre cum
