Aw mama, yan talaga ang common complaint namin sa third trimester, ang perineum area gets so stretched at sensitive na parang hirap na hirap! Since kasi you had induced labor with your first, you didn't experience the natural stretching na nagaganap weeks before labor talaga, so this is probably new for you. A few of my mum friends complained ng soreness, heaviness, at parang prickling sensation doon around 37-38 weeks pa lang, pero honestly best to mention it sa OB mo just to make sure everything's okay and normal sa position ng baby. Malapit na talaga, hopefully smooth delivery for you this time around!
