Your Second Trimester of Pregnancy

The second trimester runs from week 13 to week 27. Many people feel better during this stage as early symptoms like nausea and fatigue often ease. Your baby continues to grow quickly, and you will likely start to feel movement. 

What to expect in the second trimester 

Changes to your body 

Hormones stabilize and energy often improves. Common symptoms include: 

• A growing belly 
• Back or hip discomfort 
• Nasal congestion 
• Heartburn 
• Leg cramps 
• Mild swelling in your feet or ankles 

Many people also feel more emotionally steady than in the first trimester. 

Your baby’s development 

During this stage your baby: 

• Develops facial features 
• Forms organs and bones 
• Begins to hear sounds 
• Starts moving and kicking 
• Gains weight and grows in length 

By the end of the second trimester your baby is about 2 pounds. 

Second trimester prenatal appointments 

You will see your doctor every four weeks unless you need more monitoring. 

Visits may include: 

• Checking your weight and blood pressure 
• Measuring your belly 
• Listening to the baby’s heartbeat 
• Urine testing 
• Discussing symptoms and any concerns 

Key tests 

Your doctor may recommend: 

• Anatomy ultrasound around 18 to 22 weeks to examine the baby’s organs and growth 
• Blood tests that screen for genetic conditions 
• Glucose test around 24 to 28 weeks for gestational diabetes 

When to call your doctor 

Seek care right away if you have: 

• Bright red bleeding 
• Strong cramping 
• Severe headache 
• Vision changes 
• Leaking fluid 
• Decreased fetal movement after you start to feel kicks
