Really Hunger

Jenn
According to all my preggo apps I'm 3 weeks 6days. Due on January 31st... But im experiencing mad hunger like every two hours... Right now I'm famished but to tired to go to kichen ... This a cliché symptom of pregnancy BUT THIS EARLY ???  I starting to think I'm a little further along... 
This was my PT at 9dpo 5 day early.... And emotional argument lead me to test ???? Thought ladies... First pregnancy
