<qa>  What is the fetal monitoring performed during therapy?During therapy, maternal pulse rate, blood pressure, uterine contractions, as well as fetal heart rate monitoring will be performed every 15-30 minutes during the first 4 hours following the start of therapy then every 2 hours during the rest of treatment period. Patients whose contractions will stop after 48-72 hours will be observed for additional 24 hours to detect if contractions appear again so that if they remain stable, then they can be discharged and asked to come for follow-up after 1 week. As we stated in a previous work 13 that vaginal progesterone was effective for preventing recurrent PTL, thus all discharged patients will be advised to continue on progesterone till completed 36 weeks gestation. In addition to progesterone treatment, all patients will be instructed to undergo periods of bed rest and, also they will be educated about the symptoms of PTL. The provided antenatal care will be at 2-weekly intervals till delivery. At any time if preterm contractions appeared re-admission with repeated treatment using the same drug will be used. At delivery, all data regarding the timing of labor onset, along with maternal and neonatal complications, will be documented.
