Ah yes, the glucose tolerance test, memang standard screening for GDM (gestational diabetes mellitus) during pregnancy! Buku Pink memang akan explain pasal this, tapi basically they want to check how your body handles sugar, so kena minum that sweet glucose drink and then they test your blood levels after. A few of us kena go through this, it's just precaution, doesn't mean anything is wrong yet, just to make sure baby and you are okay. Check with your clinic or midwife if ada any concerns about the test itself, they can explain better based on your specific situation.
