Bum wee

Sat here in bed and suddenly have all this growling and air in my stomach from the top of my ribs to the bottom of my stomach just flowing around and literally growling as if I’m hungry so I pop to the toilet and it’s watery diarrhoea?!

I don’t feel sick or ill at all and I don’t have a belly ache but I have literal bum wee, it’s been such a stressful day and I was worried about the baby, I’m 17 weeks, should I be worried?
