The second trimester—weeks 13 through 28—is often considered the most comfortable phase of pregnancy. Many early symptoms like nausea and fatigue begin to ease, and this is typically when people start to feel more energized and excited. But what changes can you expect as your body and baby continue to grow? Here’s what to know about this middle stage of pregnancy.
Common Physical and Emotional Changes
As your pregnancy progresses, your body adapts in noticeable ways. These are some of the most common second trimester symptoms:
- Growing belly and weight gain: Your uterus is expanding, and you’ll begin to “show” more.
- Breast changes: Continued enlargement and darkening of the areolas.
- Skin changes: Dark patches (melasma), a line down the abdomen (linea nigra), and pregnancy “glow” may appear.
- Round ligament pain: Stretching ligaments may cause sharp pains in the lower belly or groin.
- Backaches: Postural changes can strain your back muscles.
- Nasal congestion and occasional nosebleeds: Due to increased blood flow and swelling of mucous membranes.
- Mood improvements: Many people feel more emotionally balanced and physically capable during this trimester.
Baby’s Development in the Second Trimester
This is a crucial period for your baby’s growth and development:
- Organs mature and begin functioning.
- Your baby begins to move—and you may feel those first flutters around 16–25 weeks.
- Hair, eyebrows, eyelashes, and nails begin forming.
- Hearing develops, and your baby may start responding to sound.
Key Tests and Screenings
During the second trimester, your provider may recommend:
- Anatomy ultrasound (usually around 18–22 weeks): A detailed scan of your baby’s organs, limbs, and overall development. This is often when you can learn your baby’s sex.
- Gestational diabetes screening (between 24–28 weeks): A glucose test to check how your body processes sugar.
- Blood tests and genetic screenings, if not completed in the first trimester.
Staying Healthy
To support your body and baby during the second trimester:
- Eat a balanced, nutrient-rich diet with plenty of protein, fiber, calcium, and iron.
- Stay active with safe forms of exercise like walking, swimming, or prenatal yoga.
- Stay hydrated, aiming for at least 8–10 glasses of water per day.
- Sleep on your side, especially after 20 weeks, to improve circulation.
- Keep prenatal appointments to monitor your baby’s development and your health.
When to Contact Your Provider
While many symptoms are normal, call your OB/GYN if you experience:
- Vaginal bleeding or leaking fluid
- Severe abdominal pain or cramping
- Sudden swelling in your hands or face
- Persistent headaches, visual changes, or dizziness
- Pain or burning during urination
- Decreased fetal movement after you start feeling kicks regularly
Embracing the Journey Ahead
The second trimester is often a time of emotional connection, physical milestones, and important preparations. From nursery planning to prenatal classes, now is a great time to get ready for the third trimester and birth.
To stay on track and get personalized care, connect with your OB/GYN about any questions or concerns.
