question: Hello doctor,  I am 2.5 months pregnant now. And I have developed gestational diabetes and consulted with a gynecologist in the nearby polyclinic and made HbA1c (blood sugar monitoring test) and the result is 6.4 % reference range normal up to 6%. Before pregnancy diabetes range used to be always in normal range. Nowadays blood sugar while fasting is 130. Do I need to start insulin? I need your advice. I am 24 years old. My height is 5.2 feet and weighs around 105 kg.
