Uy, normal lang yan mama! Yung hardening ng tyan (Braxton Hicks) ay karaniwang nagsisimula around 15-16 weeks, lalo na kapag gumagalaw ka or nag-stretch ka, kaya walang dahilan mag-alala. A few of us sa mama group namin ay nakaramdam din ng ganyan early on, at ang OB namin ay sinabi na totally fine as long as walang pain or bleeding, but just to be safe, better mention it sa next checkup mo ha, especially kung nangyayari frequently or may discomfort.
