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.
