Good am! Ah yan usually normal lang yan sa pregnancy, lalo na around 6 months kasi lumalaki na talaga ang belly at nag-stretch ang skin, a few of us moms experienced the same thing! Pero kung sobrang kati or may swelling pa aside from the redness, mas better i-check mo with your OB para ma-rule out other things like PUPPP or allergy, just to be safe lang. Try keeping the area clean and dry, at some moms swear by keeping it moisturized too para less itchy. Take care!
