Normal lang yan most of the time, pero depende kung ano ang tipo ng sakit, if it's ligament pain (yung stretching sensation) or Braxton Hicks-type cramping, medyo common pa lang sa second trimester, pero if it's sharp, persistent, or may bleeding, better to message your OB agad para ma-check lang for peace of mind. Pregnancy body changes are wild, kaya importante ma-monitor mo lang talaga how you're feeling.
