Sayang, heartburn masa pregnant memang common, tapi jangan ambil ubat sendiri even yang biasa, kena check dengan doctor dulu, terutama first trimester ni. Hormones and baby growth buat stomach acids jadi naik, tapi better safe than sorry, kan? Call your clinic atau go in untuk ask, they boleh recommend apa yang safe for baby. Dalam meantime, try eat smaller meals, avoid spicy stuff, and don't lie down terus after makan, a few of us found that helped! Hang in there, mummy.
