Wondering if pregnant

Kelsie
OK guys so on last Thursday me and my bf got down and dirty however, for the past couple of days I've been having period like cramps a week before period and my period is not due until next week Friday the 27th of May. Also I been urinating no more than twice during the night, having sore boobs, and backaches. And my mother had a dream that I was preggs! Lol Could I definitely be pregnant.??
