I've been the same way. I'm 9 weeks and haven't thrown up uet, but I'm constantly nauseous and never want to eat. I have to make myself eat because all food sounds gross, and so far the nausea stays all day long. I'm hoping it'll get better closer the the second trimester!
Everyone is different, I could barely keep anything down for the first 4 months of mine and then I went to normal again, but always just try to eat something no matter how hard it ***** and do prenatal, there's no really telling when you'll get better unfortunately, welcome to pregnancy
