Vaginal Probiotics During Pregnancy After Premature Rupture of Membranes

The goal of this clinical trial is to compare the microbiota of preterm babies born after premature breaking water with full-term babies microbiota. The main questions it aims to answer are: * Is babies' microbiota differs with premature water breaking than full-term babies microbiota? * Is vaginal probiotics given to the mother influence the baby microbiota? Researchers will compare vaginal probiotics use to no treatment to see if the babies microbiota and mother microbiota is influenced. Participants will * Take vaginal probiotics between premature breaking water until delivery (group A) * Keep a diary of their symptoms and compliance to treatment (group A) * Take samples of vaginal secretions and of baby's stool (all groups)
