Second Trimester Symptoms: What’s Normal?

Second Trimester Symptoms: What’s Normal?

The second trimester is often called the “easier” part of pregnancy, but that does not mean it is symptom-free. Many moms feel more energy and less nausea, while also noticing new changes like a growing belly, round ligament pain, backaches, heartburn, skin changes, and baby movement.

This guide explains common second trimester symptoms, what may be normal, and when to call your healthcare provider.

Important: This article is for general education only and is not medical advice. Always follow the guidance of your OB-GYN, midwife, or healthcare provider.

What Is the Second Trimester?

The second trimester usually includes weeks 13 through 27 of pregnancy. During this stage, many moms begin to feel more comfortable than they did in the first trimester, but your body is still changing quickly.

Common second trimester changes may include:

  • More energy
  • Less nausea for some moms
  • A more visible baby bump
  • Round ligament pain
  • Back discomfort
  • Heartburn
  • Constipation
  • Skin changes
  • Early baby movement

1. More Energy

Many women feel more energy in the second trimester compared with the first trimester. Nausea may ease, appetite may return, and daily life may feel more manageable.

However, not everyone gets the “second trimester energy boost.” If you are still tired, you are not doing anything wrong. Pregnancy affects every body differently.

2. A Growing Belly

Your bump may become more noticeable during the second trimester. Clothes may feel tighter, and you may start using maternity leggings, belly bands, or looser dresses.

This is also a meaningful time to start taking bump photos and recording how your body is changing. The Momentiqa Pregnancy Journal Book gives you a gentle place to document pregnancy milestones, symptoms, and memories. Explore it here.

3. Round Ligament Pain

Round ligament pain is a common second trimester symptom. It may feel like a sharp, pulling, or stretching sensation in the lower belly or groin area, often when you move suddenly, cough, sneeze, or stand up quickly.

Helpful habits may include:

  • Changing positions slowly
  • Resting when pain starts
  • Using gentle stretching if approved by your provider
  • Supporting your belly when coughing or sneezing

Call your provider if pain is severe, persistent, one-sided, or comes with bleeding, fever, dizziness, or contractions.

4. Back Pain and Hip Discomfort

As your belly grows, your posture, balance, and ligaments change. This can lead to lower back pain, hip discomfort, or pelvic pressure.

Supportive shoes, gentle movement, pregnancy pillows, and good posture may help. Ask your provider before starting new exercises or using pain relief products.

5. Heartburn and Indigestion

Heartburn can become more noticeable in the second trimester. Pregnancy hormones can relax the valve between the stomach and esophagus, and your growing uterus can add pressure.

Some moms find relief by:

  • Eating smaller meals
  • Avoiding trigger foods
  • Sitting upright after eating
  • Drinking fluids between meals
  • Asking their provider about safe options

6. Constipation and Bloating

Constipation and bloating can continue into the second trimester. Hormonal changes may slow digestion, and prenatal vitamins with iron can contribute for some women.

Ask your provider about safe ways to manage constipation. Hydration, fiber-rich foods, and gentle movement may help many moms.

7. Skin Changes

During the second trimester, you may notice skin changes such as stretch marks, darker nipples, linea nigra, melasma, acne, or dryness.

These changes are common, but always ask your provider before using strong skincare ingredients, acne treatments, or retinoids during pregnancy.

8. Baby Movement

Feeling baby move for the first time can be one of the most exciting second trimester milestones. Some moms describe early movement as flutters, bubbles, taps, or tiny rolls.

First time moms may feel movement later than moms who have been pregnant before. If you are concerned about movement, ask your provider what is expected for your stage of pregnancy.

9. Leg Cramps

Leg cramps can happen during pregnancy, especially at night. They may be related to circulation changes, muscle fatigue, hydration, or mineral balance.

If cramps are frequent or painful, ask your provider for guidance. Seek care right away if one leg becomes swollen, red, warm, or painful.

10. Mild Swelling

Mild swelling in the feet or ankles can happen during pregnancy, especially after standing for long periods. However, sudden swelling of the face or hands can be a warning sign and should be reported promptly.

The CDC lists extreme swelling of the hands or face, severe headache, vision changes, trouble breathing, chest pain, fever, severe belly pain, and vaginal bleeding or fluid leaking as urgent maternal warning signs.

11. Shortness of Breath

Some mild shortness of breath can happen as pregnancy progresses. However, sudden, severe, or worsening shortness of breath should not be ignored.

Seek medical care right away if shortness of breath comes with chest pain, fainting, blue lips, fast heartbeat, or a feeling that something is seriously wrong.

12. Braxton Hicks Contractions

Some moms begin noticing Braxton Hicks contractions in the second trimester. These may feel like irregular tightening of the belly.

Braxton Hicks are often:

  • Irregular
  • Mild or uncomfortable
  • Temporary
  • Improved by rest, hydration, or position changes

Call your provider if contractions become regular, painful, closer together, or happen with bleeding, fluid leaking, pelvic pressure, or back pain.

13. Anatomy Scan Emotions

Many parents have an anatomy scan around the second trimester. This appointment can bring excitement, nerves, and many emotions.

You may want to write down:

  • Questions for the scan
  • Baby’s measurements
  • Ultrasound memories
  • How you felt seeing baby
  • Any follow-up questions for your provider

When to Call Your Healthcare Provider

Call your provider or seek urgent care if you experience:

  • Heavy bleeding
  • Fluid leaking from the vagina
  • Severe belly pain
  • Severe headache that does not go away
  • Vision changes
  • Sudden swelling of face or hands
  • Chest pain
  • Trouble breathing
  • Dizziness or fainting
  • Fever of 100.4°F or higher
  • Regular contractions before 37 weeks
  • Baby’s movement stopping or slowing once movement is being tracked

If you cannot reach your provider and symptoms feel urgent, go to the emergency room. The CDC recommends seeking care immediately for urgent maternal warning signs during pregnancy and after delivery.

How to Track Second Trimester Symptoms

Tracking symptoms can help you understand patterns and prepare better questions for your prenatal appointments.

  • Record your pregnancy week
  • Note new symptoms
  • Track food triggers for heartburn
  • Write down baby movement memories
  • Save ultrasound photos
  • List questions for your provider

The Momentiqa App is designed to work alongside Momentiqa books, helping moms organize pregnancy memories, prompts, symptoms, preparation notes, and early motherhood moments. Learn more here.

Preparing for the Third Trimester

As the second trimester continues, you may begin thinking about baby registry planning, hospital bag preparation, birth classes, and postpartum support.

  • Start or update your baby registry
  • Think about your birth preferences
  • Research pediatricians
  • Plan your baby shower if desired
  • Prepare a simple postpartum support plan
  • Continue saving pregnancy memories

After Baby Arrives

The symptoms, appointments, and milestones of pregnancy become part of your baby’s beginning story. After birth, you may want to preserve first photos, hospital bracelets, first feeding memories, and early milestones.

The Momentiqa Baby Memory Book Set helps parents document baby’s first milestones and early memories. View it here.
