Answer
You said that your "blood sugar fasting is 135 and fasting is 150". Which is it? It is possible that you have gestational diabetes, since a fasting of greater than 100 is elevated. Usually, we perform a 3 hour glucose tolerance test to determine the diagnosis of gestational diabetes. If you do have a diagnosis of diabetes, we would first try diet control before starting insulin. I would suggest that you consult with an endocrinologist before you start insulin.
