Is this Normal?

So I’m 6 weeks pregnant and I feel absolutely awful. My whole body aches and feels stiff. All I want to do is sleep. I can sleep all night and take a 5 hour nap in the day . I have no appetite and everything makes me so sick. Is this normal to feel this way? I work full time and I fell like I can’t go anymore.I also have hypothyroidism which has been controlled but now since I’m pregnant my levels are going crazy. I feel like I’m dying ...
