Possible flu or virus.

Hey ladies, i'm on my last month of pregnancy and just within this past week my body has been acting up. This is my first baby so i'm not familiar with how my body reacts baby wise. I have all the symptoms of getting sick.. My body is hot like i might have a fever, my thyroids are sore and swollen, my whole body is sore and it hurts to touch anything cold. My gums are sore (which is new) and i can't keep any food or drink down. Any advice? I have a doctors appointment in the morning but i'm worried about tonight, I sweat all last night and i slept in underwear with two fans blowing on me.
