period or pregnant ?

Tayla
So i know in nor the only woman that gets confused every month 
But This month feels different 
It's started off; just feeling emotional crying a little more fighting with my Boyfriend and that feeling a lil more anxious then normal;
Fatigue- I am never ever a sleeper through the day it's something I just can't do 
Since a few days before Christmas Iv been that exhausted I just wan for lay down and Iv been SLEEPING for over an hour!
Iv had slight little pains and period pain which doesn't usually start that early 
Now my breast are so sore  and feeling swollen it hurts to hug I don't remember them being this sore around my period ? 
It says I'm due for my period in two days shall I wait for a missed period or should I test before suggestions and any help or what you go through would be great xox
