37+5 weeks and feeling very nauseous

Hi everyone I will be 38 weeks on Friday and have just been feeling very nauseous all day long. Started last night, I woke up feeling very nauseous like I needed to throw up. But I didn't. Could not sleep and just felt very ..... BLAH not good. It has continued all day not as bad as how I felt during the night but certainly not great. Nauseous all day and no food really sounded good to eat. When I do try and eat something the nauseousness just gets worse. Anyone else feeling any type of way? Is this normal ? Do you think I'm coming down with something? Any advice?
