TMI 37 weeks (Please Help) not feeling well, a bug or labour?

Patricia

So I am 37 weeks today and have been feeling very nauseous for about the past week and was suffering with loose stool going approximately 6 times a day. 2 days ago I became constipated and had headaches and hot sweats. Today I have had sudden basically water dihorea all day, hips are in agony and can barely walk. Do you think I have a bug or could this be the beginning of labour??

Please give me some advice
