As a first time mom

Ay mama, yan ay very common sa third trimester kaya don't worry! A few of my mum friends had the same experience around that time, parang ang bebe ay nag-settle na in a certain position kaya nararamdaman mo yung tension sa pelvic area, plus the weight is really putting pressure there na. Best thing is to ask your OB about it sa next checkup, lalo na if it's really painful or if may spotting, pero usually it's just Braxton Hicks or ligament stretching talaga, your body is preparing for labor. Try warm compress, frequent position changes, and rest when you can, pero definitely check with your doctor para peace of mind mo.
