For many women, the second trimester is the sweet spot of pregnancy. As your hormones start to level out, the nausea typically eases up, your energy starts to return, and you may even notice that famous pregnancy glow everyone talks about. Your bump will start to show, you will feel baby move for the first time, and things will start to feel a lot more real.
That said, every pregnancy is different, and the second trimester brings its own set of changes to get familiar with. Here's what to expect from week 14 through week 27 — and how to feel your best along the way.
What Is the Second Trimester?
The second trimester includes weeks 14 through 27 of pregnancy. For most moms, it's the most comfortable and energizing stretch of the journey, and the one where your bump really starts to show.
Common Second Trimester Symptoms
Will Morning Sickness Go Away in the Second Trimester?
For most moms, yes, and that alone is worth celebrating. As hormone levels stabilize, nausea typically eases and energy improves. If you're still experiencing some lingering queasiness, hang in there. It usually continues to improve as the weeks go on.
Why Do I Feel Dizzy and Short of Breath?
Your heart and lungs are working harder than ever right now to support you and your growing baby, so feeling a little dizzy or short of breath is completely normal. A few things that can help:
-
Avoid standing or sitting up too quickly
-
Take it easy during physical activity and avoid getting overheated
-
Keep your blood sugar steady by eating 5 to 6 small meals throughout the day
-
If you need to rest, lie on your side until you feel better
Is Nasal Congestion Normal During Pregnancy?
It is — and it catches a lot of moms off guard. Increased blood flow to the mucous membranes in your nose can cause stuffiness and even occasional nosebleeds during pregnancy. Saline drops and a humidifier can help keep things comfortable. Skip the decongestants unless your OB-GYN has given you the green light.
What's Happening with My Teeth and Gums?
Pregnancy hormones and increased blood flow can affect your oral health, too. Looser teeth and more sensitive, bleeding gums are surprisingly common during pregnancy — but the good news is that things typically return to normal after delivery. In the meantime, be gentle with brushing and flossing, and don't skip your dental visits. If you notice severe bleeding gums, let your healthcare provider know, as this can sometimes be associated with preterm labor.
How Will My Breasts Change in the Second Trimester?
The tenderness from the first trimester usually eases up a bit — but your breasts will keep growing as milk glands expand and fatty tissue builds up in preparation for breastfeeding. You may also notice your breasts beginning to produce colostrum, the first milk your body makes during pregnancy and for the first few days after baby arrives.
What Causes Stretch Marks — and Can I Prevent Them?
As your body grows and changes, stretch marks may appear on your breasts, belly, hips, or thighs. They're incredibly common and, while there's no way to fully prevent them, they almost always fade over time. Think of them as the ultimate badge of honor — proof of everything your body is doing to bring your baby into the world.
Other skin changes in the second trimester can include:
-
Dry, itchy skin — especially on your belly (prenatal massage oil is your best friend here)
-
A faint dark line running from your belly button downward, called linea nigra
-
Dark patches on your face, known as melasma or the mask of pregnancy
-
Increased sun sensitivity — daily SPF is a must right now
Most of these skin changes fade after delivery, so try not to stress too much about them.
Why Does My Back and Body Ache So Much?
Your body is adapting to a new shape, a new center of gravity, and a growing uterus that's putting pressure on surrounding muscles — so aches and pains in your back, pelvis, hips, legs, and lower abdomen are all very common.
Here are a few ways to find relief:
-
Sit in a supportive chair and shift positions often throughout the day
-
Swap the heels for supportive, low-heeled shoes
-
Sleep on your side with a pillow between your knees
-
Stretch tight calf and hip muscles regularly
-
Try a warm bath, gentle massage, or a heating pad for extra relief
Always check with your doctor before taking any pain medication during pregnancy.
Is Swelling Normal in the Second Trimester?
Yes, mild swelling is normal during the second semester, and here's why. Your body produces about 50% more blood and fluids during pregnancy, and some of that extra fluid can show up as mild swelling in your face, hands, legs, ankles, and feet.
To ease the puffiness:
-
Put your feet up whenever you can
-
Stay well hydrated
-
Cut back on caffeine and sodium
-
Avoid standing for long stretches at a time
One thing to watch for: sudden or excessive swelling can be a sign of preeclampsia, so reach out to your healthcare provider right away if swelling comes on suddenly or feels severe.
What Are Braxton Hicks Contractions?
If your belly occasionally goes rock-hard for a few moments and then relaxes, you're probably experiencing Braxton Hicks contractions — sometimes called practice contractions. They can start as early as week 16 and are your uterus's way of warming up for labor. They're totally normal, usually painless, and don't follow a regular pattern.
Changing positions and drinking water usually helps them pass. If contractions last more than a few minutes, intensify, or start coming regularly, call your doctor — it could be a sign of preterm labor.
What About Heartburn and Constipation?
Heartburn and constipation are more common during pregnancy. As your uterus continues to grow, it puts more pressure on your stomach and digestive organs, which means heartburn and constipation can get worse in the second trimester.
A few things that help:
-
Keep eating high-fiber foods like fruits, veggies, and whole grains
-
Drink plenty of water throughout the day
-
Avoid spicy, fatty, and citrus foods if heartburn is a problem
Should I Be Worried About UTIs During Pregnancy?
UTIs are more common during pregnancy and are usually not cause for concern if treated. Pregnant women are at higher risk for urinary tract infections due to changes in the urinary tract, so it's worth knowing the signs: pain or burning when you urinate, needing to go more frequently, and cloudy or strong-smelling urine. If you think you have a UTI, call your OB-GYN — they can prescribe safe antibiotics to treat it quickly.
Is Vaginal Discharge Normal?
Yes, heavier vaginal discharge is normal during pregnancy and is usually clear, white, or slightly sticky. Do reach out to your OB-GYN if your discharge suddenly increases, changes color, smells unusual, or is accompanied by itching — those can be signs of infection that are worth checking out.
How Much Weight Should I Gain in the Second Trimester?
Most moms gain about half a pound to one pound per week during the second trimester. Your OB-GYN will monitor your progress and recommend a healthy range based on your individual starting point. Try not to get too caught up in the numbers, as consistent, steady gains are what matter most.
You’re Halfway There
The second trimester is full of milestones, and at 20 weeks, you are officially halfway (plus or minus) to your due date. Many moms report this being the “easiest” of the three trimesters – with less nausea, more energy, and lots of fun changes. As always, pay attention to how you feel and don't hesitate to reach out to your OB-GYN with any questions or concerns. No question is too small, and you never have to wait until your next appointment to get the reassurance you need.
