Ahhh yes, gastrik masa pregnant memang common lah! I had it jugak around that time, and a few of my mum friends complained pasal yang sama, perut jadi sensitive, terutama kalau skip meals or makan heavy food. Try eat small frequent meals instead of 3 big ones, avoid spicy or greasy stuff, dan minum plenty of water; tapi honestly if it's really bad or won't go away, better check dengan your doc to make sure everything's okay sebab ada certain antacids yang safe during pregnancy.
