Rumbling tummy and the runs :-(

Nikki
Has anyone else experienced this? I'm 38,+5 and today and yesterday ive had the runs and really loud rumbling tummy, dont feel poorly with it but its just annoying. I only made it to 35 weeks with my first so didn't get this first time around. Ive read it could be a sign that Labour is close. I am booked in for a c section wednesday as baby breech so I'm hoping she can hold in a little longer.
