Uy, normal lang yan sa early pregnancy! A few of us in my mommy group experienced the same bloating sa week 5-6, parang sobrang uncomfortable talaga kaya alam ko kung paano ka nakakaramdam. The hormonal changes at the way your digestive system slows down during pregnancy is usually the culprit, but para ma-ease your mind and ma-rule out kung may iba, best to mention it sa OB mo sa next visit, hindi masama mag-confirm lalo na may pain involved. In the meantime, try eating smaller meals throughout the day, drink plenty of water, and avoid too much gas-causing foods; helped sa iba ko namang kaibigan!
