Mama, dahil first trimester ka pa lang at may belly pain ka, please check with your OB as soon as you can, lalo na kung yung sakit ay persistent o lumalaki, okay? Belly twitching at slight discomfort ay common sa early pregnancy dahil sa hormones at ligaments na sumasagot sa changes, pero ang combination mo ng twitching + pain especially pag stressed or busy kailangan i-monitor ng doctor para ma-rule out kahit ano. A few of us moms experienced similar, pero iba-iba talaga ang pregnancy, so better safe than sorry. Rest when you can at stay hydrated, pero huwag mag-self-diagnose, let your OB check you out.
