Even with good glycaemic control, pregnancies complicated by diabetes carry a rising risk of unexplained late-pregnancy stillbirth that becomes significant after 38 weeks; professional guidance therefore recommends elective delivery (usually by induction) at 38–39 weeks to mitigate this risk, especially in someone with a prior unexplained fetal demise [Holman 2014, PMID 24836172; Viteri 2016, PMID 27057773]. Cesarean is reserved only for obstetric indications, so induction at 38 weeks is the most appropriate plan.
