Oo, normal talaga yan sa 3rd trimester, mommy! Hormones and the baby pressing down on your digestive system can really mess with your bowels, a few of us pregnant moms experienced it too around that time. Just make sure you're drinking enough water and eating fiber-rich foods, pero if it's really frequent or may blood, or kung nag-worry ka talaga, better check with your OB just to be safe na walang infection or other concerns, okay?
