hmm.?🙄 need help!

Yesterday was my 4th day on my period and 2nd day on the pill(BIRTH CONTROL) , me & my boyfriend had unprotected sex 2 times . He peed before each time to kill any sperm leftover . He pulled out about 30 seconds before he came and he didn't cum anywhere near my vag. or inside me. What are the chances of me becoming pregnant ?
