Really don't remember this :/

Anna
I don't know if this is pregnancy symptoms or I'm getting sick.
​ 
​I'm freezing cold with chills (24F in my house, wearing hoodie, sweat pants and slippers)
​I have a headache
​My stomach has just become upset like not throw up upset but just off.
​I'm sore. 
​No fever, I'm 98.4
​Don't know if I should be preparing for being sick or prepare to get morning sickness.
