Sakit perut di awal pregnancy memang common, especially kalau ada gastrik history like you, ligaments stretch, hormones berubah, dan stomach lagi sensitive. Tapi since you've already seen the doctor and dia confirm gastrik, that's good lah, at least you know what to manage. A few of my mum friends juga experienced something similar early on and it settled down as pregnancy progressed, especially once they avoided trigger foods. Kalau rasa worse atau ada bleeding, better check with your doc again just to be safe, tapi sounds like you're on the right track already.
