Am I pregnant?

Jessica • I`m 22 and I work two jobs, still trying to figure out life but I`m getting there.
Hey guys I'm a day away from my period and have been having some pregnancy symptoms, increased urination, back aches, mood swings, nausea, smell aversion. And the newest thing is my cat has been avoiding sleeping in my stomach which is odd because that's where she is every night. Is that a sign I really could be pregnant?
