Not pmsing and period is due tomorrow.

I usually have strong pms syptoms starting a week before my period but not this month. My period is due tomorrow and I suddenly realized at work today Im not feeling any syptoms. Just been really gassy all week. Could this be a sign or pregnancy I've also been peeing like crazy for the past 3 days and havnt been drinking a ton of fluids. Me and my bf also had unprotected sex right after my last period which was the day before my fertile window began.
