Eh, GDM readings memang kena tanya doctor sebab setiap orang lain sikit, tapi generally puasa reading should be under 5.3 mmol/L and 2 hours after makan should be under 6.7 mmol/L, tapi jangan rely on ni je, kena monitor with your doctor regularly lah because pregnancy hormones boleh affect things. Mana you being monitored? Most clinics will give you a log book and specific targets based on your case, so better ask them directly what's normal for YOU.
