Here’s what to expect when you are 34 weeks pregnant with twins:
By 34 weeks in the twin pregnancy your twins are almost 17″ (45 cm) in length from head to foot. Each baby averages the following:
Head circumference: 12.5″ (312mm)
Abdominal Circumference: 12″ (302mm)
Femur Bone Length (from waist to knee): 2.5″ (64mm) which is about the height of a US dollar bill
Each baby is about the size of a cantaloupe.
What to Expect
Typical weight gain for Mom at this point is about one pound per week (0.6kg).
Total weight gain for the twin pregnancy so far will average between 36 to 52 pounds (16.3 to 23.6kg).

If Your Twins Were Born This Week
Your twins are late preterm and the odds of survival are very good. They are in good company as many twins are born during this period. Twins born during the 34th week have an increased risk of permanent health issues but generally speaking are healthy. Twins born this week average a hospital stay (including the NICU) of about 11 days.
What to Prepare This Week
When Mom is 34 weeks pregnant with twins, it is a great time to pack your bag for the hospital if you haven’t already. Remember to take supplies for Mom, the twins, and Dad.
