Pregnant from precum?

So my boyfriend and I had protected sex a day before I ovulated. Condom and pulled out and we tested it after to confirm there were no tiny rips or holes or leakage. However prior to putting on the Condom he went inside me bare for a couple seconds ( I know bad decision) he had no prior ejeculations and peed right before we had sex. How likely is it I could fall pregnant from pre cum??

From what I’ve heard I should be fine because there would be no sperm in it.
