Welcome to the second trimester!

At 14 weeks pregnant, many moms-to-be begin to feel hungrier, more energetic, and less nauseous as early pregnancy symptoms start to subside.

Meanwhile, your baby's getting chubbier by the day, and may be starting to sprout some hair.

Your Baby at Week 14

At a Glance

Say cheese!Are you making faces at me? To welcome your second trimester, your baby-to-be can now use facial muscles to grimace and smile.

It's a boy (or girl)!Boy or girl? This week, fully developed genitals make their grand entrance. Note, however, that they still may be hard to detect on an ultrasound.

Peach fuzzIt's all about hair now as your baby's head, eyebrows, and body start sprouting some fuzz.

14 weeks pregnant is how many months?

If you're 14 weeks pregnant, you're in month 4 of your pregnancy. Only 5 months left to go! Still have questions? Here's some more information on how weeks, months, and trimesters are broken down in pregnancy.

How big is my baby at 14 weeks?

At 14 weeks, your baby is growing and developing rapidly, measuring between 3½ and 4 inches long and weighing around 2 ounces, about the size of a navel orange.

Baby is standing up straight

Growing by leaps and bounds, your baby is leaping and bounding. Now the size of your clenched fist, she's on the move almost constantly — and those movements are a far cry from those jerky twitches of last trimester (though you won't feel any of them for weeks to come). They are now ballet-like, smooth, and fluid.

Speaking of ballet, it'll be years before you'll start nagging your offspring to stand up straight — but unbelievably, she is doing it right now, without any prodding! No slouch anymore, your baby's neck is getting longer, helping her head stand more erect. This gives your fetus a more straightened-out appearance.

Baby's sprouting hair and lanugo

By week 14 of pregnancy, your baby could be sprouting some hair and those eyebrows are filling in too.

Hair growth isn't limited to baby's head, though. She is also covered with a downy coating of hair called lanugo, largely there for warmth.

But it won't be there forever. As baby fat accumulates later on in your pregnancy, it will take over the function of keeping your little bean toasty, so most of the lanugo sheds. Some babies, especially those born early, still have a fuzzy coating at delivery, but it disappears soon afterward.

Other developments this week include a roof of her own — inside your baby's mouth, that is — as well as some digestive system activity: Her intestines are producing meconium, which is the waste that will make up her first bowel movement after birth.

Your Body at Week 14

One down, two to go!

Welcome to the second trimester — (almost) every pregnant woman's favorite, and for good reason! As many first trimester pregnancy woes wane, you're most likely feeling a bit peppier and a lot more human. With any luck, your breasts aren't quite as tender as they were last trimester and your energy level is making a comeback.

More good news on the horizon: less morning sickness and fewer trips to the potty to pee. Even cooler is the fact that it may be time to start hitting those maternity boutiques because you may be starting to show — instead of looking like you've eaten too much for lunch.

That's because your uterus is finally rising out of the pelvic region and into your lower abdomen. You might even be able to feel the top of your uterus, called the fundus, if you press down right above your pelvic bone in your lower abdomen. How amazing is that?

Your 14 weeks pregnant belly

Now that you’re officially in your second trimester, it may be time to go maternity clothes shopping for real, as right around now many women go from looking a little bloated to actually “popping.”

But remember: Your 14-weeks-pregnant belly is normal no matter how big or small it is. All expectant women carry baby differently depending on their height and figure, and whether this is their first pregnancy or not. So breathe a sigh of relief and know that your baby bump at 14 weeks is perfect, no matter what it looks like! And of course, if you have any questions, check in with your provider.

Round ligament pain

For some women, a possible side effect of uterine growth is what your OB/GYN would call round ligament pain. Basically, these are pregnancy growing pains that feel like achy or sharp pains on one or both sides of the abdomen that begin to appear around 14 weeks but can strike at any time during the second trimester.

Here's why: The uterus is supported by thick bands of ligaments that run from the groin up the side of the abdomen. As your uterus grows, the supporting ligaments stretch and thin out to accommodate the increasing weight. This weight pulls on the ligaments and causes a sharp pain or a dull ache in your lower abdomen. It’s often more noticeable when you change positions suddenly, quickly get up from sitting or lying down, or cough and sneeze.

The best way to bring relief? Put your feet up and rest in a comfortable position, which should ease the strain and the pain.

Staying healthy

As if you didn't have enough pregnancy symptoms to contend with, you're also more susceptible to colds, flu, and other bugs when you're expecting. That's because nature wisely suppresses your immune system during pregnancy to keep your fetus — a foreigner to your body — from being rejected.

The key to staying healthy is to engage in some germ warfare. More than ever, the best defense is a strong offense, especially when germs are being passed around your office or home like canapés.

Wash your hands often — and carry liquid sanitizer for times when a sink's not handy — don't share drinks, food, or toothbrushes; and avoid sick people like the plague. It's okay to banish a sick spouse to the couch.

If you think you've caught something, check with your practitioner ASAP, who will treat what you've got with your special needs in mind. If antibiotics are prescribed for a bacterial infection — they're useless against viruses like colds — don't hesitate to take them because you've heard medications aren't safe during pregnancy. Many are — and getting better fast is the best medicine for your baby.

Pregnancy Symptoms Week 14

Increasing appetite Now that the nausea is subsiding, you’ve rediscovered your appetite. Do your best to eat regular, healthy meals and snacks throughout the day, which keeps blood sugar and energy stable, instead of bingeing, which causes sugar highs and subsequent sugar crashes. Read More

Stuffy nose Those pesky hormones are to blame once again: High levels of estrogen and progesterone increase blood flow to mucus membranes in the body, including the nose, which causes them to swell and soften. Try running a warm-mist humidifier while you sleep to make breathing easier. Read More

Varicose veins These large, swollen blood vessels, which often show up on your legs, are caused by the extra blood volume you produce to nourish your baby-to-be. Though you may not be able to prevent varicose veins entirely — they can be hereditary — you can help minimize them by wearing support stockings, walking throughout the day to keep blood circulating, and raising your legs above the level of your heart. Read More

Decreasing fatigue You may be feeling a renewed sense of energy now that your body has finished the task of manufacturing the placenta. So you might want to use this time to get a jump start on baby prep. Are you ready to start your baby registry? Read More

An end to nausea and vomiting If you’re like most women, your morning sickness may be coming to an end now that you’re in the second trimester. Yay! Pat yourself on the back (or tummy) for making it through the worst of the nausea. Read More

Continued breast growth, less tenderness While your breasts are still growing and changing — for instance, your areolas are probably darker and your nipples may be on “high alert” — they may not feel as achy as they did in your first trimester.

Tips for You This Week

Try pregnancy-safe nail polish

It’s generally considered safe to paint your nails during pregnancy, but some nail treatments, like acrylics, can give off a strong smell that turns your stomach. Acetone, too, may irritate your skin.

A better bet: Choose pregnancy-safe nail polishes that are water-based, non-flammable, and hypoallergenic.Get enough calcium

It does a growing baby body good, building strong bones and teeth. But calcium also does your body good too — helping to maintain solid bone density and prevent osteoporosis later in life, and lowering your risk of preeclampsia now.

So make sure you "got milk" and other calcium-loaded foods, like fortified juice, almonds, sesame seeds, soy products, green leafy veggies, canned salmon, and broccoli.Skip the tattoos

Thinking of commemorating your pregnancy by getting a tattoo? Think again. While not much of the ink or its particles will enter your bloodstream, there is a risk of infection. Not a good risk to take when you're trying to stay healthy for two.

Plus, a new tattoo that looks symmetrical on your skin might become lopsided or distorted after you regain your pre-pregnancy shape, so the end result might not be what you’d hoped.

But if you already have a tattoo, no problem — just sit back and watch it stretch! Your bikini-line butterfly might just start soaring like an eagle!Get on the move

With your second trimester comes a burst of energy. Try to take advantage! Get your light-to-moderate exercise game on to keep yourself and your baby-to-be healthy.

The American College of Obstetricians and Gynecologists (ACOG) recommends getting at least 30 minutes or more of moderate exercise per day, at least five days a week. Just remember to avoid exercising on your back now that you're past the first trimester.Time for the flu shot

Every expectant woman is pregnant sometime during flu season (generally between October and May), which is why the Centers for Disease Control and Prevention (CDC) recommends that all pregnant moms get the flu shot.

And being pregnant doesn’t increase your risk for flu shot side effects either, according to research.Get ready to gain weight

In your second trimester, your baby starts to grow in earnest. Your weight gain may pick up so that if you started your pregnancy with a normal BMI of 18.5 to 24.9, you’d add a total of about 12 to 14 pounds (give or take) during this second trimester.

For the healthiest results, keep track of your pregnancy weight within reason (but definitely don’t obsess). For consistency’s sake, try to weigh yourself at the same time every day (or every few days), preferably in the morning before you get dressed or eat.Eat plenty of protein

Try to eat three servings of protein daily to help spur new tissue for your baby-to-be.

One serving of meat like skinless chicken or lean beef, for example, should be about 3 ounces — roughly the size of a deck of cards. Other great protein sources include eggs, fish, dairy, and legumes. Medical Reviewed Reviewed July 29, 2025
