The second trimester — roughly weeks 13 through 27 — is often described as the more comfortable stretch of pregnancy for many people, as early symptoms ease and energy tends to return.
What's happening physically
Nausea and extreme fatigue commonly improve for many people during this window. A visible bump usually develops, and many feel the first fetal movements ("quickening"), often sometime between weeks 16 and 25.
Typical appointments during this window
- The anatomy ultrasound, usually around 18–22 weeks, checking fetal development in detail.
- Glucose screening for gestational diabetes, typically between 24–28 weeks.
- Regular prenatal visits, often monthly during this stage.
What the baby is doing
Major organs continue maturing, and by the end of this trimester many babies could survive with intensive medical support if born early — though full-term development still has significant growth ahead. Movement becomes more noticeable and coordinated.
Common physical changes to expect
- A growing, more visible bump.
- Skin changes like a linea nigra or stretch marks for some people.
- Mild back discomfort as posture shifts to accommodate the growing belly.
- Increased appetite as early nausea eases.
Frequently asked questions
When will I feel the baby move for the first time?
Commonly between 16 and 25 weeks, though it varies — first-time parents sometimes notice it later than those who've been pregnant before, since the sensation can be subtle at first.
Is the second trimester really easier than the first?
For many people, yes — but not universally. Some continue to have symptoms like nausea or fatigue well into the second trimester, which is still within a normal range.
