What are the chances?

Okay so me and my boyfriend had sex twice on the most fertile day of my cycle but we used condoms. The thing is for a couple of minutes we go condomless and then we put a condom. Well he didn't pee between the two times we had sex so I think his precum contained a lot of sperm that could actually get me pregnant. He says I shouldn't worry but I'm freaking out here because I was so fertile and his precum was inside of me (We totally forgot that he hadn't peed ugh) I am waiting for my period ( 11 days to go) and I am so scared. What do you all think is there any chance a pregnancy can happen?
