Prodomol Labour or Food Poisoning!?

Anyone ever fo through this? For the last 36hrs I at first thought it was mild food poisoning starting slowly....abdominal pain, ravenous hunger (eating didnt satisfy and stomach hurt more), lower cramping... very loose stools (but not diarrhea...close though). This morning I started marking my symptoms and found every 10min my stomach was cramping (food does not help).

Now it's been about 36hrs...seemed to be getting slightly better but cramping started up again after eating a bit of chicken broth and back to feeling absolutely horrible.

Also does not help my stomach feels like it's being stretched to the max.

Anyone ever experience this and be fine?!
