If you're at average risk of gestational diabetes, you'll likely have a screening test during your second trimester — between 24 and 28 weeks of pregnancy.

Should I test my blood sugar 1 or 2 hours after eating gestational diabetes?

1 hour after finishing a meal: A blood sugar of less than 130 mg/dl. Check your blood sugar when fasting and 1 hour after every meal. Call your Doctor or Diabetes Nurse Educator if your blood sugar is above 100 in the morning or above 130 one hour after meals for two (2) days in a row.

When is it too late for gestational diabetes test?

You typically get a glucose screening test between 24 and 28 weeks of pregnancy. However, your provider may want you to be screened earlier than 24 weeks if a routine urine test shows a high level of sugar in your urine or if you're considered high risk.
