Is it possible I’m pregnant ?!

Hey guys sooo I’m supposed to get my period today while I usually get it on the 5th I didn’t quite get it today either so I’m waiting till tmmro morning to take one just Incase its a little late . But I’ve been feeling nauseous ,my lower back hurts a little ,I have pelvic pain ,sore breasts. Usually 3 or 4 days before my period I get pre-menstruated cramps but nothing this time no signs of blood either .

This is my supposedly period date

This is last month when I had sex . If there a possibility I might be pregnant 🤞🏽😩 btw he just finishes in me no condoms , no birth control , no nothing.
