the 20 week scan will determine if u need an additional scan to check on baby, if all is well then u’ll have another apptment in the next 4 weeks for glucose test and then another one 4 weeks after that apptment to check for baby’s growth.
I think the next appointment will be the Oral Glucose Tolerance Test. Probably you can check the Singhealth Health Buddy app to see if they’ve scheduled the appointment for you
