If you feel like your body has turned against you at 29 weeks, the symptom list is real: shortness of breath, random contractions, backache that won't quit, heartburn after every meal. None of these are warning signs on their own. Your uterus is now displacing your internal organs upward, your ligaments are stretched to their limit, and your blood volume is 45% higher than pre-pregnancy. Uncomfortable and normal are not mutually exclusive right now.
Pack your hospital bag between weeks 32–36. Include: your birth plan, insurance cards, comfortable clothing, toiletries, phone charger, and newborn outfit.
The symptoms you're navigating now are driven by specific changes in your baby's development — and those changes are accelerating.

Week 29 brings the reality of the third trimester into full focus. The symptoms that emerge now — intense and unfamiliar — are normal physiological responses to a baby that has roughly tripled in size in the last trimester. Here's what you're likely experiencing and why.
Shortness of breath: The uterus is now pressing upward into the diaphragm. This improves around weeks 35–36 when the baby "drops" into the pelvis. Sleeping propped on pillows helps. Breathlessness during rest or that comes with chest pain warrants prompt assessment.
Back and pelvic pain: Relaxin hormone loosens the pelvic joints to prepare for birth — this creates instability and pain. Symphysis pubis dysfunction (SPD) affects up to 20% of pregnant women and is more common in third trimester. A maternity support belt, pelvic physiotherapy, and avoiding asymmetric positions (e.g. standing on one leg) help significantly.
Heartburn: The uterus compresses the stomach upward; the lower oesophageal sphincter is relaxed by progesterone. Eat small, frequent meals, avoid lying down within 2 hours of eating, and ask your provider about safe antacids.
Braxton Hicks: Practice contractions increase in frequency and sometimes intensity in the third trimester. Unlike real labor contractions, Braxton Hicks are irregular, don't increase in frequency, and ease with movement or position change. If contractions become regular (every 10 minutes or more frequently) before 37 weeks, contact your provider immediately.
Discuss birth preferences including pain management options, delayed cord clamping, and skin-to-skin at your next appointment.

At 29 weeks, your baby is approximately 15.2 inches (38.6 cm) long and weighs about 2.5 lbs (1.15 kg) — roughly the size of a butternut squash. Baby is gaining approximately 0.5 lb per week at this stage as white fat deposits build under the skin.
Common symptoms at 29 weeks: shortness of breath, back and pelvic pain, intense heartburn, frequent Braxton Hicks, difficulty sleeping, swollen ankles and feet, varicose veins, and rib pain as the uterus expands. The third trimester is physically demanding — rest is a medical priority, not a luxury.
29 weeks is firmly in the third trimester, which runs from week 28 through week 40. You have approximately 11 weeks until your due date.
At 29 weeks, baby position is not yet a significant concern — most babies move frequently and won't settle into a final position until 32–36 weeks. Breech presentation before 32 weeks is common and usually self-corrects. Your provider will begin monitoring position more closely from around 32–34 weeks.
Between weeks 28–32, your provider will typically check blood pressure (monitoring for preeclampsia), fundal height (uterus measurement to track growth), fetal heartbeat, and discuss any symptoms or concerns. You may also have anti-D injection at 28 weeks if Rh negative, and GBS swab planning will come up at 35–36 weeks.
