Aw oo, normal lang yan especially during pregnancy kasi lumalaki ang uterus at nag-compress ng nerves, plus ang hormones natin nag-affect sa skin! Sa akin it was crazy itchy sa third trimester, a few of my mum friends experienced it din. Usually nawawala after delivery, pero kung super intense na or may redness/swelling, better check with your OB just to rule out anything like allergies or gestational diabetes signs na kailangan i-monitor. Stay hydrated and try moisturizing regularly muna para makatulong sa dryness!
