Would I go to a regular doctor for this?

Little bit of TMI! But I’m 32 weeks pregnant and I’ve been experiencing diarrhea for the past couple of days but today I got a really bad sore throat, headache and I feel very weak & shaky. I’m scared I may have the flu or strep😬. I called my OB yesterday because of the diarrhea and she told me to keep a bland diet which I have, but I got new symptoms today and i was wondering if I should go to the regular doctor tomorrow to get tested for strep and the flu or if I should go to my OB? I’m a first time mom so I’m not sure what to do!
