Hi, Neither your age, diabetes, history of missed abortion or high triglycerides make you a candidate for Cesarean. You should definitely try for a normal delivery, and only if some problem arises for the baby or you during labour will the obstetrician be considering a cesarean. Is your diabetes in control, are you taking insulin for the diabetes? If so ,when was your last growth scan of baby done, and in what centile was baby growth. Sometimes with uncontrolled diabetes the baby can put on excess fat around its neck and shoulder area and cause a difficult delivery . These things will be kept in mind by the obstetrician at the time of delivery. Also if you are on Insulin, it is likely that your Obstetrician will advise Induction of labour at 38 weeks . Hope this helps. Regards.
