Week 17: Building Reserves
Baby is about the size of Pomegranate (130mm crown-rump)
Your baby is beginning to lay down brown fat — a special type of adipose tissue that will be crucial for temperature regulation after birth. The placenta is growing to match the baby's increasing nutrient demands. Sweat glands are forming, and the umbilical cord is becoming thicker and stronger.
Your center of gravity is shifting as the uterus grows, which may affect your balance. The cardiovascular system is working harder — cardiac output increases by 30-50% during pregnancy. You may notice increased sweating and feeling warmer than usual.
What is important now
Stay active but mindful of your changing balance. Start sleeping on your side if you haven't already. This is a good week to plan your anatomy scan (usually weeks 18-22).

Mental wellness
Mindfulness
Vivid dreams are very common in pregnancy and don't predict anything. They're simply your brain processing a major life change.
“Your baby is building reserves of warmth — preparing for life in your arms.”

11 weeks ago- routine
Checkpoint 1 — Mutterpass may be issued upon heartbeat confirmation
Week 19
In 2 weeks- routineWeeks 19–22
Checkpoint 2 — Screening Ultrasound
Choice between a basic biometric scan or detailed organ scan. Measures head circumference, abdominal circumference, femur length, and checks placental position.
GoalAssess fetal anatomy and growth, check for structural abnormalities, and verify placental location.
Week 28
In 11 weeks- routine
Checkpoint 1 — GDM screening
- routine
Checkpoint 2 — Rhogam if Rh-negative
Week 29
In 12 weeks- routineWeeks 29–32
Checkpoint 3 — Screening Ultrasound
Third and final routine ultrasound. Assesses fetal growth, position (cephalic/breech), amniotic fluid volume, and placental function.
GoalConfirm appropriate growth trajectory and baby's position for delivery planning.
Week 35
In 18 weeks- self pay igelWeeks 35–37
Checkpoint 1 — GBS Testing — Self-pay/IGeL
Rectovaginal swab to screen for Group B Streptococcus colonization. If positive, IV antibiotics are given during labor to prevent neonatal infection.
GoalIdentify GBS carriers to enable prophylactic treatment during delivery.
Safety: If leg cramps are severe or persistent, or if you notice swelling in just one leg, contact your provider to rule out deep vein thrombosis.
