Missed period

Jessica
Hey guys so idk what's going on in my body. I am 14 days late, feel really bloated, gassy( sorry for that) and nauseous and much more and when I look the symptoms up they all show signs of me being pregnant. I haven't taken a test and yes my fiancé and I don't use any protection so there is a possibility that I might be but could I also just be pmsing? Any information would be helpful thanks guys
