Chances of pregnancy?

Okay.. So my boyfriend is worried that I might get pregnant because I'm out of the pill and we were having a lot of sex using condoms 2 days ago, but one of them stayed on me (the condom ring was out tho) after he cumed, and the second one we used ripped but we noticed it in time and he took it out right away.. Now he is insisting that there could be some cum on his manhood and that because I'm ovulating today I could get pregnant. Any thoughts? Could I really get pregnant although he didn't cum in me at all?
