How Should Sore Throat, Head Congestion, Headache, Fatigue, Body Aches With Chills?

Hi i got sick over the weekend, started with a sore throat and light cough, the next day the cough was gone and started getting really bad head congestion and headache and fatigue, then yesterday it got worse and my body started acheing and got bad chills and hot flashes off and on, my head doesnt hurt anymore and its not as congested anymore but my body just feels soo worn out and my abdomen is sore and i feel nauseated. Should i see a doctor even though its only been 3 days?
