4Week food aversions! Ugg!! Normal?

I’m 4w2d and I’m having major food aversions! Is this normal so early? Typically I eat a lot, healthy food, breakfast, fruits, and a healthy hearty dinner, maybe halo ice cream for dessert. And I drink a ton of water. But this last week I just have not been hungry! Nothing sounds good to me. Yesterday I was hungry and felt like eating Panda orange chicken with sweet and sour sauce on it, so my husband brought a small order for me and it was like my tastebuds exploded! But I’m not hungry for anything else. Is this normal to not be hungry? Or to not crave anything?
