Pregnancy change tastebuds?

I’m 6 wks and I’ve noticed major changes in my tastebuds. Is this normal? I can taste but everything tastes dull. Chocolate tastes like metal (which I read is common), my favorite chips just taste “meh” and I just feel like I’m tasting base ingredients. Like spaghetti sauce just taste plain tomatoey. Idk. I’ve never had this with any pregnancy and I’ve read about the metallic taste but haven’t seen much about anything else with tastebuds…and so early in pregnancy..
