🌱 Baby's development this week
- Eyes moving, though fused shut
- Hearing developing — can hear muffled sounds

Quickening — the first felt movements — is typically sensed between 16–25 weeks. First-time mothers feel it later; those who
🤰 Your symptoms this week
💛 Changes in your body
- First movements possible (quickening) — feels like bubbles or flutters
- Uterus halfway between pubic bone and navel
- Back pain may begin as posture shifts
- Skin pigmentation changes accelerating
Feeling those first flutters of movement is often emotionally profound. Some women feel guilty if they don
When Will You Feel Baby Move? Quickening at 16–22 Weeks
Between weeks 16–22, most pregnant women feel their baby move for the first time — a moment often described as one of the most significant of pregnancy. Knowing what to expect reduces the anxiety of waiting.
What quickening feels like:
- First-time pregnancies: most commonly described as bubbles, flutters, or the sensation of gas — easily missed
- Subsequent pregnancies: women often recognize it earlier (16–18 weeks) because they know what it feels like
- At 16 weeks, movements are genuinely small — the baby weighs under 4 oz at this point
Why you might not feel it yet at 16 weeks:
- Anterior placenta (placenta at the front of the uterus): cushions kicks and can delay feeling movement until 20–24 weeks — this is common and not dangerous
- First pregnancy: Less experience recognizing the sensation
- Baby's position: Baby may be facing away from the front of the uterus
Regular, recognizable movement becomes clearer around weeks 20–24. There is no normal amount of movement at 16 weeks — formal kick counting begins much later (weeks 26–28). For now, if you feel something, enjoy it; if you don't, it's not a concern.
🥗 Nutrition focus
- Iron absorption tip: take iron supplements on empty stomach with orange juice
- Avoid calcium supplements within 2 hours of iron — they compete for absorption
- Continue DHA supplementation throughout pregnancy — brain development accelerates
Anatomy scan is typically scheduled 18–22 weeks — book now as appointments fill quickly.

Frequently Asked Questions: 16 Weeks Pregnant
How big is baby at 16 weeks?+
At 16 weeks, your baby is approximately 4.6 inches (11.6 cm) long and weighs about 3.5 oz (100 g) — roughly the size of an avocado. The baby is holding their head erect and eyes are beginning to move side to side, though the eyelids remain fused.
What are common symptoms at 16 weeks pregnant?+
Many women experience a welcome energy boost at 16 weeks as the worst first-trimester symptoms ease. Common symptoms: round ligament pain (sharp lower-abdominal twinges when changing position), visible bump, possible first movements, back pain, increased discharge, and nasal congestion.
When will I feel baby move at 16 weeks?+
First movements (quickening) are typically felt between weeks 16–22. At 16 weeks, it's possible to feel movement but not guaranteed — particularly in a first pregnancy. If you have an anterior placenta, movement may not be felt until 20–24 weeks. This is not a sign of a problem.
What trimester is 16 weeks pregnant?+
16 weeks is in the second trimester (weeks 14–27). The second trimester is often the most comfortable — energy has returned for many, the bump is visible but manageable, and the most intense first-trimester symptoms have usually eased.
What is the anatomy scan and when is it scheduled?+
The anatomy scan (20-week scan / fetal anomaly scan) is the most detailed ultrasound of pregnancy and checks all major organs and structures. It's typically scheduled between weeks 18–22. At 16 weeks, you're approximately 2–6 weeks away from this appointment. See week 18 for full preparation details.
