I need advice

Hey ladies so my period was supposed to start the 10th of this month and it didn't. Although I'm not a always constant I don't know what to do. My breast are hurting everyday but no sign of my period just yet. I've never had my breast hurt this much and I've read it could be pregnancy but I'm not sure. Should I take a pregnancy test? I need advice
