Hai! I understand lah, it's nerve-wracking jugak when numbers go up and down macam tu, especially when you're managing GDM. The good news is your blood sugar readings are stable yang penting, so those small fluctuations (0.2-0.5kg) are actually pretty normal in pregnancy; baby does take nutrients from your body so part of the weight loss could be that. A few mum friends with GDM also shared the same worry, and their doctors said as long as glucose levels are controlled dan baby's growth is on track (which your check-ups would show), the occasional weight dips aren't a red flag, tapi definitely mention this pattern to your doctor at your next visit lah, especially sebab you want to make sure baby's getting enough nutrients still. Keep doing what you're doing with the medication and balanced meals; the once-a-week fast food won't derail everything, so don't stress yourself out too much because stress sendiri boleh affect blood sugar! You're doing great, first-time mum, just keep those monthly check-ups regular okay.
