Summary

This study tests whether a daily oral synbiotic (a mix of probiotics and prebiotics) can help women with a history of preterm birth carry their baby longer. About 400 pregnant women will take either the supplement or a placebo from early pregnancy. The goal is to see if the supplement improves vaginal health and reduces the chance of delivering too early.
