Ay, totally normal yan momsh, especially at 33 weeks! A few of us dito sa group nag-experience din ng ganyan, parang muscle soreness talaga kasi ang pelvic area mo is nag-stretch at nag-prepare na for delivery, plus ang weight ng baby pulling down. Ang sakit na parang from work-out, that's actually your ligaments adjusting, kaya yung hirap maglakad at umakyat ng stairs super relatable. Try pelvic support belt (game-changer talaga!), rest when you can, at mainit na compress kung kailangan mo, pero best pa rin na i-mention mo ito sa OB mo next check-up para sure lang na wala namang iba at may peace of mind ka, 'kaya? You're almost there, momsh!
