2nd Trimester Pregnancy

Physical Changes in the Second Trimester

During the second trimester, many women notice their bodies growing and adjusting to support the developing baby. The belly becomes more visible as the uterus expands to make room for the baby. Breasts grow larger and may feel more sensitive. Wearing a supportive bra and comfortable maternity clothes helps with daily comfort. Common symptoms in this stage include:

  • Back Pain: As the uterus grows, it can cause lower back pain or discomfort. Supportive shoes with low heels can help.
  • Braxton Hicks Contractions: Some women feel mild, irregular tightenings in their abdomen. These are usually painless and go away, but regular or painful contractions should be reported to a healthcare provider.
  • Skin Changes: Hormones may darken parts of the skin. Many see a dark line (linea nigra) down the belly and darker patches on the face called melasma. Stretch marks can appear on the stomach, hips, or breasts. Spider veins may show up on the legs or face.
  • Nasal Symptoms: Stuffy nose and nosebleeds are more likely due to changes in blood flow and hormone levels. Saline sprays or a humidifier often help.
  • Dental Health: Gums may bleed more easily. Gentle brushing, flossing, and rinsing with salt water can help.
  • Dizziness: Changes in blood flow can make you feel dizzy. Moving slowly and staying hydrated can lessen symptoms.
  • Leg Cramps: These are common, especially at night. Stretching before bed and wearing comfortable shoes can help.
  • Vaginal Discharge: You may notice more clear or white fluid. This is usually normal, but unusual color or odor should be checked by a healthcare provider.
  • Urinary Tract Infections (UTIs): You may have a higher risk of UTIs, which can cause pain when urinating or a strong urge to go. Seek prompt treatment to avoid complications.

DizzinessStand up slowly, hydrate, lie on side
Breast tendernessSupportive bra, adjust bra size
Vaginal dischargeSeek care for pain or odd color/smell
UTIsPrompt medical care if symptoms

Other changes can include mild swelling in the hands or feet. Some women develop varicose veins or spider veins, while hemorrhoids might appear due to increased pressure. You may also notice “quickening”—the first noticeable movements of the baby. These little flutters can make the pregnancy feel more real.

Appetite may increase as the baby grows. Many women feel relief from morning sickness, while some still have occasional nausea or heartburn. Eating smaller meals, avoiding spicy foods, and drinking water can help. If vomiting or diarrhea becomes severe, let your healthcare provider know.

List: Additional Symptoms That May Develop

  • Heartburn and indigestion
  • Headaches
  • Leg and foot swelling
  • Mild shortness of breath
  • Pregnancy “glow” or increased oiliness in skin
  • Achiness in pelvis or hips as the body prepares for delivery

Changes in Mood and Emotions

Many women notice their energy levels improve and fatigue fades compared to early pregnancy. Nausea often lessens, and a sense of excitement or optimism might take the place of earlier worries. Mood swings can still happen due to hormonal changes.

Feeling anxious about labor, delivery, or becoming a parent is common. Reading reliable resources, attending childbirth classes, and making a support plan can help ease worries. Depression or anxiety may develop during pregnancy, even if this is not a first pregnancy. Talk openly with healthcare providers if feelings of sadness or anxiety interfere with daily life. Getting support can make a big difference.

Taking time for self-care—rest, exercise, healthy food, and enjoyable activities—can improve mood. Connecting with family or joining prenatal groups online or in person can also help.

Checklist: Preparing for What’s Ahead

  • Consider registering for childbirth classes (some may be online).
  • Review maternity leave policies at work.
  • Begin thinking about if and how to breastfeed.
  • Start looking into childcare options if needed.
  • Discuss a support system with family, friends, or a partner.

Medical Visits and Second Trimester Care

Regular prenatal care continues throughout pregnancy, with several checkups during the second trimester. At these visits, your provider checks weight gain and blood pressure, and measures the size of the uterus (fundal height) to track the baby’s growth.

Your provider may listen to the baby’s heartbeat and talk about symptoms you may be experiencing. If you want, you can find out the baby’s sex during a mid-pregnancy ultrasound. This ultrasound also checks for fetal development and structural concerns. You may have blood tests or screenings for gestational diabetes, anemia, and infections during this trimester.

If you are carrying twins, your provider may schedule more frequent monitoring. Flu and COVID-19 vaccines are recommended if you have not already received them. Vaccines can protect both you and your baby, and those living with you should also stay up to date.

Sometimes, you may have the option for virtual prenatal visits if your pregnancy is low-risk. For telehealth appointments, keep a list of questions ready, and consider using a home blood pressure monitor or scale to track important details.

Table: Typical Second Trimester Tests and Procedures

Test/ProcedurePurpose
Ultrasound (around 18-22 wks)Fetal anatomy, growth, sex determination
Blood test for gestational diabetesScreen for high blood sugar
Fundal height measurementTrack uterine and fetal growth
Urine testsCheck for infections, preeclampsia
Blood pressure monitoringScreen for hypertension

Call your healthcare provider right away if you have symptoms like bleeding, strong abdominal pain, severe headache, vision changes, or sudden swelling. Quick attention is important for rare complications like preeclampsia or preterm labor. Keep taking prenatal vitamins, especially those with folic acid, iron, and calcium. Stay hydrated and eat healthy meals to support both you and your baby.

Gentle exercise, such as walking or swimming, can help with physical changes and mood, but check with your provider before starting anything new. Kegel exercises can strengthen your pelvic muscles and may help with bladder control. Good rest is important, and sleeping on your left side can help with circulation.

Quick Tips for Prenatal Care in the Second Trimester

  • Keep all prenatal appointments, whether in person or online.
  • Track weight gain and report major changes.
  • Continue taking prenatal vitamins.
  • Report any new symptoms (bleeding, cramping, fever).
  • Ask about any vaccines needed.
  • Prepare questions for each visit.
