Hi dr I am 32 Years
And now 5 week pregnant also.
Weight Journey: Reduced from 66.5 kg to 57.5 kg in 3 months (Jan to March).
Medical History:
HbA1c in December: 7.0% (Fasting sugar was between 98–116 mg/dL)post meal always below 120 in glucometr.Recent HbA1c (March 22): 5.6% (Achieved through only diet and exercise).
Current Diet Plan:
Lunch: 4 tablespoons of Rice + High Protein (Fish/Egg/Pulses) + Salad.
Breakfast & Dinner: 1 or 2 small portions of Wheat or Ragi.
Frequency: Eating small portions every 2–3 hours.
Since April, my home glucometer shows readings below 100 mg/dL (Fasting: 91–97, Post-meal: 89-95). In January, these were consistently between 110–120 mg/dL. Is it possible my glucometer is faulty, or is this drop normal due to my weight loss and early pregnancy? current and same diet sufficient for the baby's development?which test should i perform to get my actual glucose level at this stage ogtt or norml blood test??

Please regularly check your sugars.
As doctors have said - its a great metabolic success. However a very restrictive diet may not be the right way to go in terms of pregnancy and nutrition. Do consult your gynac regularly.
Remember to get a healthy exercise along with nutritional management.
Next Steps
It would be advisable to consult a good nutrionist who can walk you through this.

A lower glucose trend can happen in early pregnancy because pregnancy changes insulin sensitivity, and weight loss can also lower glucose levels. Home glucometers can also vary enough that a change of 10–20 mg/dL may reflect device and timing differences rather than a true major shift.
Please don't worry or panic this is absolutely normal but to be safe do a venous plasma sugar level in laboratory.
Next Steps
Please book an appointment for further details if any and follow up with regards to your sugar control and monitoring through video consultation.
Health Tips
Kindly eat healthier diet mostly of protein rich, complex carbohydrates, and green leaves. Ensure to visit obstetrician for routine pregnancy tests, and scan during the early till the delivery. Make sure to do OGTT between 24 -28 weeks unless if any risk factors like your FBS, PPBS has any variations.

Its very unlikely to consider glucometer faulty , its normal physiology , in first 3 months of pregnancy , insulin sensitivity is increased bit , you have controlled diet and good weight loss are also key factors in your case , but i will advice to increase more complex carbs in diet during pregnancy , don’t go for extensive weight loss , for fetal well being nutrition matters more ,
Next Steps
Just do fasting bsl once at lab to crosscheck meter &Do 75g OGTT at 24–28 weeks

Your current glucose readings are actually very good and expected given your recent weight loss and improved lifestyle. The drop from HbA1c 7.0% to 5.6% is significant and reflects true metabolic improvement, not a faulty glucometer.
In early pregnancy, especially around 5 weeks, there can be increased insulin sensitivity, which can further lower glucose levels slightly. So your fasting (91–97 mg/dL) and post-meal (89–95 mg/dL) values are well within target range and reassuring.
Your diet pattern is disciplined, but it appears slightly restrictive for pregnancy, particularly carbohydrates. Completely keeping post-meals
Next Steps
For testing:
At this stage, routine fasting and postprandial blood sugar is sufficient
OGTT is typically done at 24–28 weeks unless high risk
Since you had elevated HbA1c earlier, you may consider an early OGTT (now or in 1st trimester) for baseline
Continue monitoring fasting and 2-hour post-meal sugars (weekly or twice weekly)
Get a lab-based FBS + PPBS once to validate glucometer readings
Consider early OGTT due to previous HbA1c 7%
Slightly liberalize diet:
Add a bit more complex carbs (fruit, whole grains)
Ensure adequate calories for pregnancy
Start/continue prenatal supplements (folic acid, etc.)
Follow up with obstetrician + physician/endocrinologist
Health Tips
Avoid over-restriction of diet—baby needs adequate nutrition

• Fasting:
