Chance of getting pregnant?

So my man and I had sex for about 3 hours today. He did not ejaculate except in my mouth and we stopped having sex after that. We did not use a condom at all. He urinated after his last ejaculation before we met up today(last time he ejaculated was last Monday) but I AM ovulating. Since he didn't cum in me and pissed after the last time we had sex, what are the real odds I could get pregnant after today? We won't be doing this again without protection.
