Stomach bug or labor?

M

I live an hour and a half from my hospital and we just happen to be in the same town as my hospital today celebrating my birthday. We were at the movies and I felt super sick... went to the bathroom and threw up everywhere and had diarrhea (sorry tmi). My stomach is in knots and churning I constantly feel like vomiting. Should I go to labor and delivery? I’m 39 + 2 today. I don’t want to go over a stomach bug but I also don’t want to get home and have to turn back around if it is the start of labor
