FREAKING OUT. PREGNANT?

Hi everyone. So me and my boyfriend had unprotected sex (withdrawal method) a maybe 4-5 times this month. I've been busy with work and tired so we usually don't. Sometimes he has sex with me in my sleep(I think it's okay, and kind of hot, so don't lecture me about how I'm not consenting). My period is 2 days late and it's NEVER late. Ever. My period was early last month but it usually comes around this time. What do I do?!?!?! We're both 18, I turn 19 next month. He says he pulls out way before he ejaculates when I'm asleep so there's no possible way I could be pregnant right??
