Twin Pregnancy Week by Week: an Overview

Twin Pregnancy Week by Week: an Overview

Congratulations, you’re having twins! Week by week, your two babies are getting ready to meet you, and you’re also on an exciting (yet exhausting) journey toward the day you’ll welcome your sweet babies home. It can be helpful to know the major twin pregnancy milestones that await you.

Early Signs of Twins

In the first few weeks, you might notice signs of pregnancy such as tender breasts, fatigue, nausea, and a missed period. A home pregnancy test can confirm your hunch that you're pregnant, and an ultrasound scan at your provider's office will reveal you are actually carrying two babies. After the initial surprise, it’s completely natural to feel overjoyed, overwhelmed, or even shocked for a while.

There are two different types of twins: identical and fraternal. You will no doubt wonder how similar your twins will be and what having twins will entail.

Twin Pregnancy Symptoms in the First Trimester

When you’re pregnant with twins, you might experience more intense pregnancy symptoms in the first trimester (until about week 13) such as morning sickness, frequent urination, and food cravings or aversions.

During these first weeks and months, each of your little ones develops from a cluster of cells to a tiny fetus with a heart, spinal cord, head, and limbs.

Second Trimester Signs of Twins

Twin moms-to-be usually get larger sooner, and during this trimester, it will become more obvious that you are having twins. You might find you are more uncomfortable and tired than singleton moms during the second trimester. Extra weight gain is also completely normal — after all, your body is a nourishing home to two little babies.

During weeks 14 to 27, your twins are also busy growing, developing a sleep-wake cycle, and learning sucking and swallowing motions. During this time, feel free to talk or sing to them. Your babies will be listening intently as they gain the ability to hear.

The Last Stretch — Literally

In the third trimester, you might experience swelling in your hands and feet and itchy skin on your belly, and you might find it hard to sleep or walk comfortably.

Meanwhile, your twins are getting ready for the big day! They are learning to recognize your voice, and are likely to be getting into the optimal position for a vaginal delivery, which means both babies have their heads down. However, with twins, there’s a higher chance of needing a C-section.

Even though you might have checked our due date calculator, be aware that on average, twins are born closer to week 36 than to week 40, so it’s worth getting prepared early. Search and match twin baby names with the help of our Baby Name Generator. Then take time to baby proof your home and car, and pack your hospital bags. Get organized for those first few weeks at home with your newborns by making sure you have doubles of all the clothes, cribs, and diapers you’ll need.

Your Twins Can’t Wait to Meet You!

Expect labor to be longer than with a single baby. If your twins arrive early, they might need a little extra time in the hospital before doctors can be sure they’re ready to go home.

Twins come with their share of challenges, but they’re definitely a treat. So, although handling two newborns will be exhausting at times, you’ll be amazed how your heart will grow for these babies you have nurtured all along the way.
