35 weeks and no appetite

I'm 35weeks 2 days and have zero appetite over the past 2 days. I don't have a fever. I'm able to keep food down. It just doesn't sound appealing. I'm pregnant with twins so I know I need the calories. I am still eating I just have to force it down... I have not had this issue since the morning sickness in the first trimester! Is this a sign I'm getting sick?! Or just a normal part of pregnancy.
