Ay oo, ganyan din ako nung third trimester kasi super init at humid, plus ang friction from walking at sitting lang, napakalaki ng pregnancy rash dito talaga! A few of us mums tried keeping the area dry as much as possible (cotton underwear, loose clothes, fan on), at isa sa mga kaibigan ko swears by letting it air out when she could at using plain powder, pero honestly kailangan mo talaga i-check with your OB kasi baka may underlying yeast infection or something na kailangan ng proper treatment, lalo na kasi itchy na. Better safe na, lalo na ngayon na pregnant ka pa lang!
