Uy, worry mo ay valid talaga, mama, pag may ganitong symptoms, mas better ka mag-check sa doctor mo agad, lalo na may paulit-ulit na tae. Hindi ko ma-say kung normal lang yan or need ng medical attention, pero alam ko na ang OB mo ang best mag-assess. A few of us moms din nag-experience ng tummy issues during pregnancy, pero kailangan talaga ma-rule out ang iba pang concerns, kaya please don't delay pag-doctor visit, ok? Better safe than sorry, especially at 4 months ka pa lang. Fingers crossed for you!
