Sex during ovulation

My fiancé and I BD the whole week or so of my fertile window and according to app I ovulated last Saturday the 3rd. We’re not preventing nor trying for a baby we’re kinda just going with the flow and whatever happens is fine :) we use the pullout method so no sperm gets in me (at least we don’t think so) and has been working for us. But this time he came and some got on/around my 🐱 and was just wondering could there be a possibility I could get pregnant? And how soon do you think I can test?
