Aww mama, 23 weeks na pala, that's when the baby is getting bigger and pushing on your stomach, kaya talagang common ang acid reflux dito sa pregnancy! A few of us moms tried eating smaller, frequent meals instead of three big ones, and staying upright after eating, pero if sobrang lala na talaga, best to mention it to your OB sa next check-up kasi they might suggest safe antacids for pregnancy or other options na swak lang sa inyo. Hang in there, usually it improves after delivery!
