Background: Braxton Hicks contractions are the term for false labor pains. False labor contractions can easily be mistaken for true labor as the delivery date approaches and you begin to look for signs of impending labor. However, unlike true labor contractions, Braxton-Hicks contractions will not gain in intensity, length, or frequency over several hours. They often stop altogether with an increase in hydration or walking. These contractions are not working to soften or open the cervix and will not lead to additional labor signs. True Labor pain comes at regular intervals and, as time goes on, gets closer together. Each lasts about 30-70 seconds, contractions continue despite movement, contractions increase in strength steadily, and pain usually starts in the back and moves to the front. Patients and Methods: This is a prospective study that was conducted on 410 pregnant women at term (38 to 42 weeks) presenting to the Obstetrics emergency unit at El-Zarqa Central Hospital and Damietta specialized hospital for labor check participated in this prospective study after oral and informed consent. Results: There was a significant increase in gestational age associated with a significant decrease in cervical length in women presented with true labor pain when compared with women with false labor pain. Conclusion: The trans-vaginal cervical length measurements were important to detect labor and show a statistically significant value in the prediction of labor and to differentiate between true and false labor pain. The shortest cervical length is considered more specific for the prediction of true labor pain.
