Ugh I'm miserable

So the past couple days I have been having some pretty strong Braxton hicks but nothing consistent and nothing I can really time. We'll today I feel like I have the flu or something my body aches and I constantly feel like I need to go to the bathroom and I have no appetite and constantly nauseous . I'm 38 weeks 5 days. Is this normal or should I call my OB? I thought I was past this constantly feeling sick stage in my pregnancy.
