Our Baby Journey29 weeks pregnant
29 weeks pregnant is about 6½ months. It falls in the seventh month of pregnancy. You are in week 29 of 40, in the third trimester. Here is what is happening with your baby and your body this week.
Your baby is about the size of a butternut squash.
Length: about 38.6 cm (15.2 in) from crown to heel · Weight: about 1.15 kg (2.5 lb)
Your baby at 29 weeks
Muscles and lungs keep maturing. The bones are fully developed but still soft.
Your baby's bones are fully formed but still soft and flexible. They are absorbing calcium from your blood to become stronger. The skull remains soft, with spaces between the bones, so the head can mold to pass through the birth canal.
Muscles and lungs continue to develop, and your baby's head is growing to make room for the expanding brain. Layers of fat are building up under the skin, which will help your baby stay warm after birth, when they need to regulate their own body temperature for the first time.
Your baby's movements may feel stronger and more like jabs and pushes than flutters. As your baby grows and space in the uterus becomes more limited, you might notice that movements change from big kicks to more rolling and stretching. The type of movement may change, but your baby should keep moving regularly.
Your body at 29 weeks
You may feel short of breath as the uterus presses upward on your diaphragm.
As your uterus presses upward on your diaphragm, you may feel short of breath, especially when climbing stairs or lying down. Good posture and resting can help. You might also notice more back pain, constipation, and hemorrhoids, as the uterus presses on your bowels and blood vessels. Some people experience heartburn, frequent urination, and swelling in the legs and feet. Your body is also producing more blood, which can make you feel warm. Some people develop varicose veins or itching skin.
Your belly at week 29
In month 7 (weeks 28–31) your belly grows noticeably and may start to feel heavy. Stretch marks may appear. Fundal height is usually around 28–31 cm.
Belly size and shape vary a lot depending on your build, whether this is your first pregnancy, your baby's position and the amount of amniotic fluid. At checkups your doctor or midwife may measure your fundal height to track your baby's growth, and may arrange an ultrasound if the measurement is quite different from what they expect.
Symptoms at 29 weeks pregnant
- Shortness of breath
- Stronger, more noticeable baby movements
- Constipation and hemorrhoids
- Frequent urination

Checkups around week 29
Routine prenatal visits often happen every two to three weeks now. If you did not receive the whooping cough vaccine yet, your provider may offer it. If you are Rh negative and did not receive anti-D at 28 weeks, it may be given now. Timing varies by country.
Tips for week 29
- Sit and stand up straight to give your lungs more room.
- Eat calcium-rich foods to support the baby's bones.
- Take breaks and avoid overexertion.
Common symptoms in the third trimester
The third trimester runs from week 28 until birth, usually around week 40. Your baby gains most of their weight, their lungs mature, and your body prepares for labor. Not everyone has every symptom, and it is normal for symptoms to come and go. Common ones include:
- Shortness of breath as your uterus presses up on your diaphragm
- Braxton Hicks (practice) contractions
- Swelling of the feet and ankles
- Trouble sleeping and getting comfortable
- Pelvic pressure and pain
- Needing to urinate more often again
- Heartburn and back ache

Frequently asked questions
How big is my baby at 29 weeks pregnant?
At 29 weeks pregnant, your baby is about the size of a butternut squash. That is about 38.6 cm (15.2 in) from crown to heel, weighing about 1.15 kg (2.5 lb).
How big is my belly at week 29 of pregnancy?
In month 7 (weeks 28–31) your belly grows noticeably and may start to feel heavy. Stretch marks may appear. Fundal height is usually around 28–31 cm. Bump size, shape and when you start to show vary a lot from person to person.
Why am I short of breath at 29 weeks?
Your growing uterus pushes up on your diaphragm, the muscle under your lungs, leaving less room for them to expand. Pregnancy hormones also make you breathe more deeply. This breathlessness is usually normal. Sit and stand up straight and take breaks. Contact your doctor right away if breathlessness is sudden or severe, or if you have chest pain, a racing heart, or cough up blood.
How much calcium do I need at 29 weeks?
Adults aged 19 and over, including during pregnancy, are generally advised to get about 1,000 mg of calcium a day; younger teens need more. Good sources include dairy products, fortified plant milks, tofu made with calcium, canned fish with soft bones, and leafy greens. If you do not get enough from your diet, your doctor or midwife may recommend a supplement.
Is it normal to feel warm all the time at 29 weeks?
Yes. Increased blood volume and a higher metabolic rate can make you feel warmer than usual and sweat more. Dress in light layers, drink plenty of water, and avoid overheating. If you have a fever, feel unwell, or have other symptoms, contact your doctor or midwife.
