What is the Second Trimester?

The second trimester spans weeks 13 to 28 of pregnancy, meaning you’re already a third of the way through this amazing journey! It’s a time when your baby is growing rapidly, and you’ll begin to feel more connected to your pregnancy as you start to experience some magical milestones (hello, baby kicks!).

Once I get into the second trimester, I was actually happy to be pregnant! I started counting down the weeks until we were able to meet out little nugget with this adorable picture frame!

Common Second Trimester Symptoms

Even though many women find the second trimester more manageable, some symptoms persist or change. Here are the most common ones you may encounter:

Increased Energy

Say goodbye to the first trimester fatigue! Many women find their energy levels bouncing back during this period. This is the perfect time to tackle those nursery projects, take long walks, or simply enjoy life. I took walks around the neighborhood in the evening, so that the Florida sun did not take my energy away! Check out these shoes, they are light, comfy, and slip on, my go to shoes while I was in my second trimester.

Growing Belly

By the second trimester, your baby bump is officially making its debut. Your uterus is expanding to accommodate your growing baby, and for many moms, this is the time when maternity clothes start to become a necessity. I got every color of these pants- Trust me on this one!

Braxton Hicks Contractions

While actual labor is still a ways off, you might experience Braxton Hicks contractions—mild, irregular "practice" contractions that help prepare your body for labor. They’re usually nothing to worry about but make sure to talk to your doctor if they become painful or frequent.

Round Ligament Pain

As your uterus grows, it puts pressure on the ligaments supporting it, causing sharp, quick pains in the lower abdomen or hips. This is normal, but stretching or changing positions can help alleviate the discomfort.

Glowing Skin

Ever heard of the "pregnancy glow"? Increased blood flow and hormonal changes can leave your skin looking brighter and healthier than ever. Time to take all the compliments!

Swelling

Some women experience mild swelling in the legs, ankles, and feet. This is due to increased blood flow and fluid retention, but it’s usually nothing to worry about unless the swelling becomes excessive. I personally felt the most swelling in my fingers, no rings for me until after baby was born!

Nasal Congestion

Believe it or not, "pregnancy rhinitis" is a thing. Hormones cause the mucous membranes in your nose to swell, leading to stuffiness or congestion.

Baby Development During the Second Trimester

Your little one is going through some incredible transformations during these weeks! Here’s a look at the key developments happening during this exciting trimester.

Week 13: Baby Can Hear You!

By the end of week 13, your baby’s vocal cords have developed, and they’re starting to hear the sounds from the outside world. So, go ahead and talk, sing, or play your favorite music—your baby is already listening.

Fun Fact: By week 13, your baby’s tiny vocal cords are forming, but they won’t actually make any sounds until after birth.

Week 16: Movements Become Noticeable

Around week 16, you might start feeling those first flutters of movement, known as "quickening." These baby kicks are still soft and delicate, but they’ll become more noticeable as the weeks go on. Some moms describe it as feeling like popcorn popping or butterflies in their belly.

I descripted this beautiful and odd feelings as feeling like someone was pushing against your belly from the inside.

Week 18: Gender Revealed

If you’re eager to know your baby’s gender, you’ll typically find out around week 18 at the anatomy scan! Your baby’s reproductive organs are now developed enough to tell whether you’re having a little boy or girl.

Week 20: Halfway There!

You’ve officially reached the halfway mark (if you are having one)! At week 20, your baby is about the size of a banana and has started developing unique fingerprints. They’re also practicing swallowing and even hiccuping in the womb!

Fun Fact: Your baby is covered in a waxy coating called vernix, which helps protect their delicate skin from becoming wrinkled in the amniotic fluid.

Week 24: Viability

At 24 weeks, your baby has a good chance of surviving if they were to be born prematurely, though they would still need medical care. This is an important milestone in pregnancy, as it marks "viability."

Fun Fact: Your baby is now forming taste buds and can even begin to taste what you’re eating via amniotic fluid!

Fun Facts About the Second Trimester

Who doesn’t love fun pregnancy trivia? Here are some light-hearted and fascinating facts about the second trimester:

Baby’s Hair is Growing

Yes, your baby might already have some hair by the end of the second trimester! Whether they’ll be born with a full head of locks or barely-there wisps, that hair starts growing around week 14. Baby’s eyebrows and eyelashes also start coming in during the second trimester!

You’re Carrying More Fluid Than You Think

By the second trimester, your body is retaining up to 50% more blood than it did pre-pregnancy to support your growing baby. No wonder you’re feeling a bit more bloated! I never felt the 'normal' bloating feelings during the second trimester, instead I felt and notice the difference in my thighs.

Your Baby Can Yawn

Around week 18, your little one starts yawning in the womb—because growing is hard work! You might even catch a glimpse of it during an ultrasound. Babies yawn, hiccup, and suck their thumb while still in the womb.

Your Baby’s Eyes Can Sense Light

Although their eyes are still closed, your baby can sense light through the womb starting around week 16. Shine a flashlight on your belly, and they may even move toward it. Even though babies can sense light, their eyes won’t fully open until the third trimester.

Babies Can Respond to Your Voice

By week 18, your baby’s ears are fully formed, and they can hear your voice. Studies show that babies can even recognize their mother’s voice and language right after birth. Time to start practicing those lullabies!

Tips for a Happy and Healthy Second Trimester

While the second trimester is typically the most enjoyable, it’s still important to take care of yourself. Here are a few tips to keep you feeling your best during this time.

Stay Active

Moderate exercise is great for both you and your baby. Whether it’s a prenatal yoga class or a brisk walk, staying active can help boost your energy and mood.

Focus on Nutrition

Now that the morning sickness is fading, you can focus on eating a balanced diet full of fruits, veggies, and lean proteins. Remember, your baby is growing fast, so they need all the nutrients they can get!

Stay Hydrated

Drinking plenty of water helps reduce swelling, prevents dehydration, and supports your increased blood volume. Aim for at least eight glasses of water per day.

Sleep Comfortably

As your belly grows, finding a comfortable sleep position might get tricky. Try using a pregnancy pillow for extra support, and make sure to sleep on your side for optimal circulation.

The second trimester is an exciting time filled with new symptoms, magical baby developments, and memorable milestones. From feeling those first kicks to watching your bump grow, this phase of pregnancy is one to cherish. Don’t forget to take care of yourself and enjoy every moment as you prepare to meet your little one. You’re halfway there, mama!
