Sayang, jangan panik dulu, sebab doktor yang prescribe ubat tu tahu you're pregnant, so dia assess dulu risk vs benefit. One dose won't cause harm, okay? Tapi untuk peace of mind and to monitor everything closely, confirm dengan doktor you again about the medication, ask if you need to continue it or if ada safer alternative for your weeks. Most of my mum friends yang kena gastrik during pregnancy managed with doktor's guidance, and babies fine je. Doctor knows best, trust them, and if you're really worried, request follow-up scan. Jangan stress sangat, stressing is also not good for baby.
