could i be pregannt

my predicted period was due 5 days ago (i have very irregular cycles tho) my predicted ovulation was the 25th of june and the next day i had unprotected sex 3 times. the first time he pulled out about 5 minutes before he finished and i blew him. then he went to the bathroom and a little while later we fucked again. he pulled out before he came. shortly after (5-10) minutes i started blowing him and then we fucked. he pulled out but i’m worried that some of his precut may have had sperm in it. i’m only 17 and yes ik i should be in birth control or i should be using condoms and all that so don’t come at me with that. but what is the likelihood that i could be pregnant?
