At 17 weeks pregnant, you're halfway through your second trimester. This period is crucial for your developing embryo, who is now called a fetus. During this time, your body is undergoing significant changes to support the growth of your baby. Let's dive into what's happening to your fetus and your body at 17 weeks pregnant.
Fetal Development at 17 Weeks
Your fetus measures approximately 5.4 inches (13.7 cm) in length and weighs around 5.9 ounces (167 grams). At this stage, their major organs and body systems continue to mature.
Sensory Development
The sensory development of your fetus is accelerating. Their eyes are forming, and although they are still closed, they can detect light and darkness. The eyelids are fused shut to protect the developing eyes, but they can sense movement and respond to stimuli.
The ears are also developed enough to detect sounds outside the womb. Your fetus can hear your heartbeat, breathing, and even external noises like music or voices. This is an excellent time to start talking to your baby and playing soothing music to stimulate their auditory development.
Motor Skills and MovementAt 17 weeks pregnant, your fetus is becoming more active. They can swallow, kick, and even suck their thumb. Their muscles are developing, and they can make voluntary movements like curling their toes or grasping their feet.
You might start feeling these movements, often described as gentle fluttering or bubbling sensations. This is an exciting milestone, as it's a sign that your fetus is growing and developing properly.

|---|---|
| Length | 5.4 inches (13.7 cm) |
| Weight | 5.9 ounces (167 grams) |

Physical Changes in Your Body
At 17 weeks pregnant, your body is undergoing significant changes to support the growth of your baby. Your uterus has expanded to the size of a small melon, and your skin is stretching to accommodate your growing belly.
You might experience some physical discomforts, such as back pain, round ligament pain, or Braxton Hicks contractions. These are normal symptoms, but it's essential to discuss them with your healthcare provider to ensure everything is progressing smoothly.
Nutritional Needs
During this period, it's crucial to maintain a balanced diet rich in essential nutrients. Focus on consuming:
- Leafy greens like spinach and kale for folate and iron
