Ns,sperm and now pregnant?

Oh my God! Did I really do that ....? Yes, I just did it with a patient of mine AO. I was just too horny during my break and urgently needed sex. And in the middle of fucking I pissed on him too .... But he didn't mind because he found it really cool my warm piss. And he just sprayed his sperm into my dripping wet fuck hole after my Golden Shower! But am I pregnant from him now and why did I just piss on him in the middle of sex? I hope my boss doesn't find out about it... otherwise I'm out of a job as a nurse!
