Ay, indigestion during early pregnancy is super common, nakakaabala talaga! I'd still suggest checking with your OB first para ma-recommend niya ang safest option for you and baby, kasi may certain antacids na okay lang pero iba-iba depende sa situation mo. From what a few of us tried, simple lifestyle changes like eating smaller meals, avoiding spicy or fatty foods, at drinking plenty of water throughout the day really helped, plus staying upright after eating. Some of my mum friends swear by ginger tea o plain crackers, pero of course, always clear it with your doctor muna, better safe than sorry during pregnancy!
