Uy, normal lang yan sa 36 weeks, marami sa amin ang nakaramdam ng ganitong pagsakit, parang pressure or cramping sa area na yan kaya ang dami naming napag-usapan about it sa aming group! Pero since you're already so far along at having pain na significant, mas better kung i-mention mo sa OB mo next visit para sure lang na walang iba, baka Braxton Hicks ka lang or positioning ng baby, pero it's good to rule out anything else. Marami ring naging ligtas and normal yung pregnancy nila kahit ganyan, so don't worry too much pero do ask your doctor, okay?
