Hello I need help here I'm new

Been having cramping for the past almost 2 weeks off and on. Been nauseous and sleeping a lot more and a lot more tired. Eating a lot more. Sore breasts And just have a feeling that I am pregnant. I hope so. I hope aunt flow ain't just messing with my head. I also usually only cramp a day or two before I start my period. My last period was on the 18th of December and only lasted 3 days. What's your opinion aunt flow or pregnancy
