could I be pregnant?

So my period is late by 6 days. My boyfriend and I have had sex basically all of last week and this week too he doesn't cum in me but he also doesn't pull out fast enough. Here's been times where when we're done having sex he gets paper and cleans my vagina and says this stupid "oops" then he tells me to go pee like if that's going to help. So could I be pregnant ?
