Hi My Name Is Jordyn, I'll Be 35 Weeks On

Hi my name is Jordyn, I'll be 35 Weeks on Tuesday. For the last few days I've been feeling out of it. Extremely nauseous but haven't gotten sick. Feel like I have no appetite and have constant hot flashes. Also have a tea colored pee so I am trying to drink more water but it seems like the more fluids I drink the more nauseous I get :/ my brother had a fever the other day and was sick but I have no fever or anything. Just a little worried.
