Aiyoh, this is so common in early pregnancy, especially first trimester, morning sickness lah tu, even though it happens anytime of the day! Most of my mum friends went through the same thing around 8-9 weeks, and it usually gets better after week 12 or 13. For now, try eating small frequent meals instead of big ones, and keep sipping water slowly, sometimes having a full stomach makes the nausea worse. The pedih ulu hati (heartburn) is also very normal sebab pregnancy hormones affect your digestion. Tapi kalau you're really struggling to keep anything down and feeling super dizzy or weak, kena check with your gynae okay, just to make sure everything's fine with the baby and you're not dehydrated.
