Aaah alam ko yan, sobrang uncomfortable talaga! Marami sa amin dito na nagkaroon ng acid reflux during pregnancy kasi ng hormones at yung bigat ng baby sa stomach area, one of my mum friends said it got really bad sa third trimester niya. Try eating smaller, frequent meals instead ng malalaking pagkain, and avoid spicy or fatty stuff muna; a few of us swore by drinking milk or eating yogurt din to ease it, plus sleep with your head elevated if kaya. But if it's really bothering you and affecting your eating, better check with your OB kasi they can recommend safe options for preggies na talagang makaka-tulong!
