Ineffective management of blood glucose (BG) levels during preconception and pregnancy has been associated with severe maternal and fetal complications in women with type 1 diabetes (T1DM). Preconception care emphasizing stringent glycemic control in the preconception period and continued through early pregnancy can dramatically reduce these risks. However, the use of preconception care in the US has been disappointingly low due to a variety of organizational, provider, and patient centered factors. Furthermore, efforts to achieve tight glycemic control can increase the risk of severe hypoglycemia (SH) in T1DM women, potentially leading to serious health consequences. In this project, the investigators will test an education based Internet intervention (Bump2be or Blood glucose awareness training (BGAT) for users who might become pregnant) for use with T1DM women who are either actively trying to become pregnant (TP) or planning to become pregnant in the 12 months following their enrollment in this study (PP).
