Ay, mommy, better check with your doctor about that pain, hindi ako makakapag-diagnose, but any tummy pain in pregnancy is worth getting checked out talaga, especially when it's connected sa movement. Better safe than sorry, lalo na ngayon ka na sa 23 weeks! A few of my mum friends had similar concerns, at lahat sinabi nila na relief ang isip nila after the doc checked them, so don't worry, you're doing the right thing by asking. Pabotin mo lang agad si doctor or obstetric clinic mo, okay? Take care, mama!
