Weak and shaky

Is feeling really shaky and weak no matter how much you eat or drink water a symptom of early pregnancy??? I’ve been having a lot of other symptoms as well like extreme nausea but I dont feel I am I’ll just having symptoms if that makes sense. And some others too but I’m not gonna list them all. But I can hardly eat anything or even drink water so I have to take small sips throughout the whole day and I’ve been able to handle smoothies, applesauce, and salads. And I’ve been eating a bit of chicken here and there for protein but not a whole lot. And it’s like nothing will make this shaky and weak and light feeling go away. I still have a week before I can test but I so badly want to be pregnant and it’s killing me to wait hahah. Is this an early symptom has anyone else felt like this???
