TTC ADVICE??!!

Ca
Okay so the last couple of days my appetite has been so off, like I'm always starving!! I'll eat and get so full, then an hour later I get so sick feeling from being just so darn hungry. 
Also, my stomach has been cramping but not often. 
I've been having terrible back pains!
And I've been like really constipated, which is odd because I always use the bathroom normal. 
Annnd, I've been going pee back to back. 
Super moody, I'm a super nice person but I've noticed I've been like really prissy acting lately. 
I've been TTC for a couple of months now, and I'm scared to take a prego test because Idk if I can face another negative:( 
Do these sound like prego symptoms ?? Or am I just getting my hopes up too high??
