Summary

This study tests whether adding a vaginal tablet containing good bacteria and a low-dose hormone (Gynoflor®) to standard preterm labor treatment can help women stay pregnant longer. About 80 pregnant women between 24 and 33 weeks will receive either the tablet or a placebo for 6 days. The main goal is to see if more women remain pregnant beyond 7 days after starting treatment.
