AM I PREGNANT

so I’ve had unprotected sex with my boyfriend for a couple of months now but he has never cummed in me and I’m only 17. I haven’t even had a period this month which is wayyy late. I’ve been a little stressed lately and moody but it still hasn’t come. also my best friend had a dream LAST night and she said that she was pregnant in her dream but she’s a virgin so there’s no way she’s pregnant. was that a sign? am I pregnant?
