ClinConnect Summary

This clinical trial is investigating how Doppler ultrasound can measure blood flow in the uterine arteries during the first trimester of normal pregnancies. The goal is to understand how changes in this blood flow might help predict the risk of miscarriage. Researchers will be looking at healthy pregnant women and those with a history of repeated miscarriages. By comparing blood flow data from different groups, they hope to gain insights that can help improve care for pregnant women.

To participate in the study, eligible women must be confirmed to have a single pregnancy with a heartbeat at 6 weeks, and they should have complete medical records. Women who have had multiple pregnancies, certain uterine conditions, or chronic health issues will not be included. Participants can expect to undergo ultrasound examinations and provide information about their health and pregnancy history. This research could lead to better understanding and management of pregnancy-related risks in the future.
