Sex??

My friend and I had sex and he didn't use protection at first but when he got close and I was pleased he put one on.. he peed before we had sex. And had not cummed prior. He had told me that there was no precum since he had peed and hadn't cummed again. Chances of pregnancy? It was right after my period ended. Cannot take pregnancy test. Just curious of If it's likely. I know it's possible. Just wondering the likelihood
