36 Weeks Pregnant with Twins

Here’s what to expect when you are 36 weeks pregnant with twins:

Fetal Development

By 36 weeks in the twin pregnancy your twins are each 5 pounds (2.3 kg) and 18″ (46 cm) long. They each average the following measurements:

Head circumference: 13″ (327mm) about the size of a grapefruit
Abdominal Circumference: 12.75″ (322mm)
Femur Bone Length (from waist to knee): 2.7″ (69mm) which is about the height of a US dollar bill

Each baby is about the size of a canary melon.

Allison S – “I am 35 weeks and 6 days, so almost to 36 weeks! Our identical twin girls weigh a half a pound difference so far. I’ve been experiencing small contractions, but feel okay overall and they both have good heart rates.”

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 36th 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 7 days.
