in 34 weeks pregnancy I am feeling to go motion again and again 2 to 3 times with mild stomach irritation.

A. Diarrhea during the third trimester is not as uncommon and is more likely to happen as you approach your due date. It could be a sign that labor is near, and it can occur right before labor or a couple of weeks before labor. If it is a couple of weeks before your due date, a premature birth should not be expected.
