Trying not to worry

Michaela • 31 years old. Mom of 3

31 weeks today and I have been having gas pains and diarrhea for the last 3 days (no more than 2 times a day, and this is the only time I've had diarrhea this pregnancy). I'm not sick, I feel otherwise normal and normal diet and bowel movements. Baby is moving around fine. I know it can be a sign of labor approaching but it's too soon. Anyone else having this problem?
