Oo normal yan sa early pregnancy, lalo na ang bloating at constipation dahil sa hormone changes, pero yung recurring pain na yan parang worth checking with your OB kasi baka may something else going on, especially if it's triggered by water, better safe than sorry sa pregnancy! A few of us moms noticed ang same bloating and digestive issues pero nag-settle na after first trimester, pero yung pattern mo sounds like something your doctor should know about para ma-rule out any concerns.
