Normal yan mostly dahil sa hormones at lumalaking baby, pero since may constant na tiyan pain at digestive issues ka, mas better na i-check mo sa OB mo para sure lang, sometimes it could be constipation lang na common sa pregnancy, pero better safe than sorry, hihi. Try drinking more water, eating fiber-rich foods like fruits and veggies, and moving around a bit kasi nakakatulong talaga sa digestion at sa balakang pain. Hoping you feel better soon, mama!
