Hay, that itching with the discharge can be normal pregnancy thing kasi ang hormones mo ay nag-a-adjust, pero honestly di ko masiguro kung bacterial infection or yeast overgrowth lang yan, better mag-check ka with your OB agad para sure at ma-treat properly if kailangan, especially since nag-iitch ka na. A few of us got similar situations during pregnancy at ang OB lang talaga ang nakapag-diagnose ng tama, so don't worry, call na lang your clinic!
