Females, age 18-40 y.o., diagnosed with type 1 diabetes and currently using an insulin pump, will be provided a study continuous glucose monitor (CGM) in order to collect 3 full menstrual cycle data within 180 days. Enrollment may last from 3-5 months. Study participants will include free-cycling females and females following oral contraceptive therapy. Study CGMs and activity trackers will be provided for the entire data collection period. During data collection, all participants will be asked to record meals consumed and free-cycling females will be asked to confirm ovulation by means of study-provided ovulation kits. The Clue app will be recommended to study participants to record dates of beginning of menses and ovulation (if applicable).
