At 22 weeks pregnant, you’re solidly in the second trimester, and both your body and your baby are changing fast. Your baby is roughly the length of a papaya, measuring about 11 inches from head to heel and weighing close to a pound. This is the week many parents start feeling more consistent movement, and your bump is now visible enough that strangers may start noticing.
How Your Baby Is Developing
The most visible milestone this week is hair. Your baby’s eyebrows and hair on the head are now visible, giving the face a more defined, recognizable look. Beneath the skin, fat deposits are slowly building up, which will eventually help regulate body temperature after birth. Right now, though, your baby is still lean, and the skin appears wrinkled because it’s growing faster than the fat underneath it.
Your baby’s senses are sharpening. The inner ear structures responsible for balance are maturing, and the auditory system is developed enough to pick up sound. Your heartbeat, digestion, and voice are the primary soundtrack. Some parents start talking, reading, or playing music to their baby around this time, and while your baby can’t understand any of it, the rhythm of your voice is becoming familiar. The eyes are formed but the eyelids remain fused shut for a few more weeks.
Lungs are developing but are far from ready to function outside the womb. Tiny air sacs are forming, and your baby is practicing breathing motions by inhaling small amounts of amniotic fluid. This “practice breathing” helps the lungs prepare for the real thing months from now.
What Movement Feels Like Right Now
Most people begin feeling fetal movement around 20 weeks, so by 22 weeks you’re likely noticing kicks, rolls, or fluttery sensations more regularly. The movements may still be inconsistent. Some days you’ll feel a lot of activity, other days very little. That’s normal at this stage because your baby is still small enough to shift into positions where kicks are harder to detect.
Formal kick counting isn’t recommended until the third trimester, around week 28, when reduced movement can signal that the baby is in distress. For now, simply getting familiar with your baby’s general patterns is enough. You’ll likely notice more activity after meals or when you’re lying down at night.
Changes in Your Body
Your uterus has grown to about the level of your belly button. From this point forward, your care provider will likely start measuring fundal height, the distance from your pubic bone to the top of your uterus. At 22 weeks, that measurement should be roughly 22 centimeters, give or take 2 centimeters. It’s a quick, low-tech way to confirm your baby is growing on track.
Other changes you may be noticing:
- Stretch marks and skin changes. As your belly expands, pink or reddish streaks may appear on your abdomen, breasts, or thighs. Some people also develop a dark line running down the center of the belly, called the linea nigra.
- Swelling in the feet and ankles. Increased blood volume and fluid retention make mild swelling common, especially by the end of the day.
- Back and hip pain. Your center of gravity is shifting, and the hormone relaxin is loosening your joints in preparation for delivery. Together, these put new strain on your lower back and pelvis.
- Gum sensitivity. Between 60% and 75% of pregnant women develop gingivitis during pregnancy. Hormonal changes increase blood flow to the gums, making them red, swollen, and prone to bleeding when you brush. Keeping up with regular brushing, flossing, and dental visits is especially important right now.
Braxton Hicks Contractions
Some people start noticing Braxton Hicks contractions around this time. These are practice contractions: a tightening sensation across the front of your belly that comes and goes without a regular pattern. They tend to be mild, and you can usually keep talking, walking, and going about your day while they happen. Changing positions or taking a short walk typically makes them stop.
Real labor contractions behave differently. They come at regular intervals, get stronger and closer together over time, last between 30 and 90 seconds each, and don’t ease up when you move. The pain also tends to radiate to the lower back or cervix rather than staying localized in the front of the belly. If you experience regular tightening that intensifies, a dull persistent low backache, pelvic pressure, vaginal spotting, or a gush or steady trickle of fluid, contact your care provider immediately. These can be signs of preterm labor.
Iron and Nutrition
Your blood volume is expanding significantly to support your baby, and that means your iron needs are higher than usual. The recommended daily intake during pregnancy is 27 milligrams, but the typical diet only provides about 15 milligrams. That gap is one reason prenatal vitamins include iron supplementation.
When your body’s iron stores start running low, the early signs are subtle: fatigue that feels disproportionate to your activity level, trouble concentrating, and changes in your hair or nails. If it progresses to iron deficiency anemia, symptoms become more noticeable, including extreme fatigue, pale skin, shortness of breath, dizziness, rapid heartbeat, and cold hands and feet. A routine blood draw during the second trimester can catch this before it becomes a problem.
Beyond iron, this is a good time to focus on calcium for your baby’s developing bones, omega-3 fatty acids for brain development, and staying well hydrated. Dehydration can worsen Braxton Hicks contractions and contribute to headaches.
Ultrasounds and Testing
If you had your anatomy scan around week 20, your provider may have already reviewed the results with you. This detailed ultrasound checks your baby’s organs, spine, limbs, and the placenta’s position. Sometimes, though, the baby’s position during the scan makes it hard to get a clear view of everything. Factors like amniotic fluid levels, body type, or scar tissue can also obscure certain details.
If your provider couldn’t see everything they needed, a follow-up ultrasound around 22 weeks is common. This doesn’t necessarily mean something is wrong. It often just means the baby was curled up in an awkward position and the sonographer needs a second look. If the anatomy scan did reveal something that needs monitoring, your provider will explain what was found and what the next steps look like.
What to Start Thinking About
At 22 weeks, delivery still feels far off, but this is a practical window to start making plans. If you haven’t already, now is a reasonable time to begin researching childbirth education classes, since many fill up weeks in advance. It’s also worth starting to think about your preferences for labor and delivery, even in broad strokes, so you have time to discuss them with your provider.
If your workplace requires paperwork for parental leave, getting familiar with the process now gives you a buffer. The same goes for setting up a nursery or buying larger items. The second trimester is generally when energy levels are at their best during pregnancy, so tackling these tasks now can feel a lot easier than waiting until the third trimester, when fatigue, size, and discomfort tend to ramp up.
