Anyone else feeling really crappy/sick but not sick??

So I’m 38 +3 and I have felt soo sick the last few days but don’t have a fever, not vomiting (though I feel I could), no couch or runny nose! Just basically feeling sick without actually being sick. Also at night my body is in so much discomfort I’m tossing and turning and can’t sleep.. I can’t shake the feeling of just feeling WEIRD.... my dr thinks I may be contracting while I’m sleeping and that’s why I can’t sleep very well and feel weird.. this is my 3rd and I’ve never had this happen... I woke up this morning feeling like I was gonna have the runs but could barely get anything out.... felt nauseous and was cramping, but it went away... I’m still only 50% and 1 cm (I’ve been that for 3 weeks) idk I literally just feel off... I can’t shake the feeling either.
