Ay, importante talaga yan need mo i-check with your OB, especially since may paninigas ka na rin! At 23 weeks, basta regular ang check-ups mo at okay lang ang baby sa ultrasound, usually hindi pa big deal kung saan siya positioned kasi maraming oras pang gumagalaw sila, pero yung paninigas, yun na ang kailangan i-monitor talaga ng doctor. One of my friends had similar concerns at sinabi ng OB niya siguro stress or Braxton Hicks lang, pero kailangan verified ng professional, hindi lang based sa worry.
