Most pregnancy calculators are based on single pregnancies and may not be accurate for twins. We have developed a set of evidence-based tools specific to twin pregnancies – for estimating fetal growth percentiles, monitoring gestational weight gain, assessing protein requirements, and evaluating delivery-related risks. These tools are used in our clinic and are available here for families and care providers.

 

 

  1. Cervical Length And The Risk Of Preterm Birth in Twin Pregnancies
  2. Estimated Fetal Weight Percentiles Calculator for Twin Pregnancies
  3. Maternal Weight Gain in Twin Pregnancies
  4. Protein Requirement for Women with Twin Pregnancies
  5. Risk of Cesarean Section in Patients Undergoing a Trial of Vaginal Twin Delivery
  6. Risk of Having a Large Fetus in Pregnancies with Diabetes
