Preggers?

My last period was the 22-29 of November. We had unprotected sex 3 days in my fertile window, one of which was my ovulation day. Currently, my breasts have hurt SO bad the past few days! Slight cramping which is unusual this time of month for me. I’ve also been super tired and hungry. Some stuff makes me nauseated too which doesn’t happen. I’ve been urinating a lot more the past few days too. I’m not due for my period for another 7 days. Help!?
