This study uses Continuous Glucose Monitoring (CGM), a tiny device that checks blood sugar all the time, to spot and manage high blood sugar in pregnant women early on. The study aims to see if high blood sugar causes problems like big babies, baby injuries, or high blood pressure in moms.

Women with a single pregnancy will wear a hidden CGM sensor before 14 weeks and 6 days. This sensor checks if their blood sugar is too high. If their blood sugar is high, they might join a special group to get treatments. If it's not high, they will just be watched.

• The study takes place in early pregnancy and lasts until 16 weeks 6 days.
• Participants will need to wear a CGM sensor and attend regular appointments.
• There are no known risks from wearing the CGM sensor.

To join, you must be 18 or older, have a single pregnancy, and not have had gestational diabetes before. You should also be able to read English or Spanish. Some medical conditions and medications might prevent participation.
