I am type 2 DM on oral medication. Now I am preganant. Since I am on tablets instead of insulin can I continue my preganancy?

Yes. Some of the oral meds actually decrease the risk of miscarriage. Others do carry some risk and will need to be changed. There is also a chance that you will need to be put on insulin at some point in the pregnancy but you can with close monitoring have a healthy pregnancy and a healthy baby. Best of wishes.
