Ay anak, ganyan talaga usually kapag may gas sa tiyan or hindi pa sanay ang digestive system mo, a few of us mums noticed na especially during first months postpartum, parang bumalik lang yung tummy namin sa "high school mode" haha! But kung persistent yung sakit at nakakaabala na talaga, better mag-check ka na sa doctor para sure, babe, kasi minsan pwede ring constipation or something na kailangan ng proper check-up lang.
