At 14 weeks, you’re crossing into the second trimester, and for many women this is where pregnancy starts to feel noticeably different. Your baby is about the size of a lemon, roughly 3.5 inches long from crown to rump and weighing around 1.5 ounces. Meanwhile, your body is shifting gears: the nausea that dominated the first trimester is likely fading, your energy is returning, and your belly is just starting to make its presence known.
How Your Baby Is Developing
This week marks a significant milestone in your baby’s blood development. Red blood cells are now forming in the spleen, taking over a job previously handled by other temporary structures. Your baby’s neck is becoming more defined, giving the head a more distinct shape rather than sitting directly on the shoulders. Facial features continue to refine, and the muscles in the face are developing enough for tiny expressions.
Your baby’s sex is also becoming clearer this week, though it may not be visible on ultrasound for a few more weeks depending on positioning. At 3.5 inches and about 1.5 ounces, your baby has roughly doubled in size over the past two weeks and will continue growing rapidly through the second trimester.
Morning Sickness and the Energy Shift
If you’ve been counting the days until nausea lets up, week 14 is often the turning point. Morning sickness tends to improve right around now, as the second trimester begins. Most women find it subsides significantly, though some experience lingering symptoms into the early weeks of the second trimester. If you’re still feeling queasy, that’s within the range of normal, but the trend from here is generally toward relief.
With nausea easing, many women notice a real boost in energy. The exhaustion of the first trimester, driven largely by the rapid hormonal changes your body was adjusting to, starts to lift. This middle stretch of pregnancy is often called the “honeymoon trimester” for exactly this reason. You may find yourself sleeping better, eating more comfortably, and feeling more like yourself than you have in weeks.
What Your Body Looks Like Now
Your uterus has grown enough that the top of it (the fundus) is now sitting just above your pubic bone. For some women, especially those on a second or third pregnancy, this means a visible bump is forming. First-time moms may not show much yet, since the abdominal muscles haven’t been stretched before. Either way, your lower belly will likely feel firmer than usual.
Hormonal skin changes are ramping up, too. The placenta is producing a hormone that stimulates melanin production, the pigment that gives skin its color. This is why your areolas may be noticeably darker and why some women start seeing the early signs of a linea nigra, the vertical dark line running down the belly. That line typically becomes clearly visible closer to 20 weeks, but the process is already underway. The same melanin increase can cause darker patches on the face, sometimes called the “mask of pregnancy.” None of these changes are preventable since they’re tied directly to the hormonal shifts of pregnancy, but they usually fade after delivery.
You might also notice your skin looks a bit more luminous. The so-called pregnancy glow is real: increased blood volume and oil production give the skin a flushed, slightly dewy appearance.
Round Ligament Pain
One new sensation you may encounter around this time is a sharp, stabbing pain on one or both sides of your lower belly. This is round ligament pain, and it’s one of the most common complaints of the second trimester. The round ligaments are bands of tissue that support your uterus, and as the uterus expands, these ligaments stretch longer and wider. The problem comes when you move suddenly, because the already-taut ligaments contract faster than they can comfortably handle.
Common triggers include standing up quickly, rolling over in bed, sneezing, coughing, or laughing. The pain is typically brief but can be surprisingly intense. To ease it, try holding your belly or flexing your hips before you sneeze or cough, move more slowly when changing positions, and consider wearing an elastic belly band for extra support. Gentle stretching and warm (not hot) baths also help. Acetaminophen is generally considered safe for severe episodes.
Nutrition in the Second Trimester
Your calorie needs are increasing, but not as dramatically as you might expect. In the second trimester, you need about 340 extra calories per day compared to your pre-pregnancy intake. That’s roughly a Greek yogurt with granola and fruit, or a handful of nuts with a piece of toast. The “eating for two” idea significantly overstates what’s actually needed.
What matters more than calorie count is the quality of those calories. Your baby’s skeletal system is developing rapidly, so calcium and vitamin D are important. Iron needs are climbing as blood volume increases. Protein supports the rapid tissue growth happening in both your body and your baby’s. If first-trimester nausea kept you from eating well, now is a good time to reintroduce variety since your stomach is likely more cooperative.
Exercise and Core Work
The second trimester is generally a comfortable window for staying active. If you were exercising before pregnancy, you can usually continue with modifications. Walking, swimming, prenatal yoga, and light strength training are all well-suited to this stage.
Core exercises deserve some extra thought. Planks and similar abdominal work may still feel fine at 14 weeks, but keep an eye out for “coning,” which is when the center of your stomach visibly bulges or protrudes during a movement. That’s a sign the exercise is creating too much pressure on the abdominal wall and could worsen a separation of the abdominal muscles called diastasis recti. If you notice coning, switch to a modified version like a knee plank or a wall plank. As your belly grows larger through the second trimester, you’ll want to shift to doing exercises on a slight incline rather than lying flat on your back.
Screenings Coming Up
If you had first-trimester genetic screening (typically done between weeks 10 and 13), you may be getting those results around now. The next round of optional testing, called the quad screen, is a blood test that checks for markers related to Down syndrome, Edwards syndrome, and neural tube defects. It’s performed between weeks 15 and 22, so your provider may discuss it at your next appointment. This is a screening test, not a diagnostic one, meaning it identifies risk levels rather than giving definitive answers. If results come back with elevated risk, further testing such as amniocentesis would be offered.
Week 14 is a natural point to start thinking about your upcoming anatomy scan, which usually happens between weeks 18 and 22. That’s the detailed ultrasound where your baby’s organs, limbs, and growth are thoroughly evaluated, and where many parents learn the sex if they want to know.
