Cramping and Nausea at 35 weeks

Jessica

I am 35 weeks today and all day yesterday I had on and off period like cramping in my lower abdomen and tightness right under ribs, as well as nausea, diarrhea (sorry, I know TMI), and shortness of breath. I drank a ton of water last night and went to bed and felt fine. Now the nausea, tightness under my ribs and shortness of breath is back. Time to call my OB?
