Nausea subsides, energy returns, and the first baby movements arrive. But the second trimester also brings new physical changes worth knowing about.

After the exhausting and emotionally demanding first months, the second trimester of pregnancy usually brings relief. For many expectant mothers, nausea and fatigue gradually disappear, appetite improves, and the pregnancy becomes more visible. During this period, the first baby movements often occur, initially like a gentle fluttering or bubbles, and later becoming clearer and stronger, as reported by Ordinacija.hr.
Although the second trimester is often considered the most pleasant period of pregnancy, the enlargement of the uterus and hormonal changes can cause back pain, leg cramps, skin changes, dizziness, and other discomforts. According to Mayo Clinic guidelines, most of these changes are a normal part of the body's adaptation.
The second trimester typically lasts from the 14th to the 27th week of pregnancy, although the boundaries may vary slightly depending on medical sources. During this period, the baby grows rapidly and develops senses, reflexes, and movements. The pregnant woman increasingly feels physical changes, but still does not have the heaviness and discomfort typical of the final months.
One of the most anticipated moments of the second trimester is certainly the first baby movements. Initially, movements may feel like fluttering, bubbles, gentle pulsing, or digestive sounds, so they are not always easy to recognize. Most pregnant women begin to feel them between 16 and 24 weeks. In a first pregnancy, movements may only become clear after the 20th week, while women who have given birth before sometimes recognize them earlier.
If you have not felt movements by the 24th week, you should inform your gynecologist. Once a regular pattern of baby movement is established, it is important to monitor changes. There is no universal number of movements that applies to all pregnancies; rather, it is crucial to know your baby's usual rhythm. If you notice that the baby is moving significantly less or movements have completely stopped, contact the maternity ward or your doctor immediately. Do not delay until the next day or rely on a home device for listening to the heartbeat, warns NHS guidelines.
The growing uterus shifts the body's center of gravity, while pregnancy hormones affect the relaxation of ligaments. This can lead to pain in the lower back and sacrum. Comfortable shoes with low heels and adequate support, along with proper posture and avoiding prolonged standing, can be helpful. When lifting objects, bend your knees and keep your back straight. Pain that is severe, sudden, or continuous, especially if accompanied by bleeding, fever, painful urination, or contractions, requires contacting a doctor.
In the second trimester, some expectant mothers experience occasional feelings of tightness in the abdomen, known as Braxton-Hicks or practice contractions. They are usually irregular, mild, short-lived, and do not progressively intensify. If you are before 37 weeks and contractions become regular, painful, more frequent, or stronger, contact your doctor because they may indicate preterm labor.
Increased hormone levels can boost the production of melanin, the pigment that gives skin its color. Dark brown or gray patches may appear on the face, known as melasma, and a dark line from the navel to the pubic bone, called linea nigra, may develop. Sun exposure can further darken pigmentation, so it is recommended to use a broad-spectrum sunscreen.
During pregnancy, blood volume and hormone levels increase, which can cause swelling of the nasal mucosa. This leads to congestion and occasional nosebleeds. Hormonal changes can make gums more sensitive, so they may bleed during brushing or flossing. This is not a reason to avoid oral hygiene; during pregnancy, it is crucial to brush teeth regularly and visit the dentist.
Changes in blood pressure and circulation can cause dizziness, especially when standing up suddenly or after prolonged standing. Try to change positions slowly, eat regularly, and drink enough fluids. When you notice dizziness, it is advisable to sit or lie on your side to avoid the risk of falling. Since weakness and dizziness can indicate anemia, your doctor may check your blood count if necessary.
Painful calf cramps often occur at night. Although their exact cause is not always known, they may result from changes in blood flow, muscle strain, and uterine expansion. Sudden pain in one leg accompanied by swelling, redness, or warmth is not a typical muscle cramp and requires urgent medical evaluation due to the possibility of a blood clot.
During pregnancy, you may notice an increased amount of clear or white discharge that has no strong odor. Such discharge is often normal and serves to protect the vagina from infections. Contact your gynecologist if the discharge has an unpleasant or very strong odor, becomes green, yellow, gray, or bloody, is accompanied by itching, burning, pain, or tenderness, or becomes extremely watery. Very fluid discharge can be difficult to distinguish from amniotic fluid, so any suspicion of leakage should be checked immediately.
In the second trimester, a detailed ultrasound examination of the fetal anatomy is usually performed. The duration and scope of the examination may vary depending on the healthcare system, the progress of the pregnancy, and the gynecologist's opinion. During the examination, the baby's growth and structure, the position of the placenta, and other key developmental signs are assessed. Sometimes the baby's sex can be seen during the examination if the parents wish and if the baby's position allows it.
According to the NHS, in their system such an examination is usually performed between the 18th and 21st week of pregnancy. The World Health Organization recommends at least one ultrasound examination before the 24th week to assess gestational age, detect multiple pregnancies, and improve the detection of potential abnormalities. It is important to keep in mind that ultrasound cannot detect all health problems.
Contact your doctor, maternity ward, or emergency services immediately if you notice vaginal bleeding, suspected leakage of amniotic fluid, severe or persistent abdominal pain, regular or increasingly strong contractions before 37 weeks, high fever, severe headache, vision problems, sudden swelling of the face and hands, difficulty breathing or chest pain, pain, redness, and swelling in only one leg, a significant decrease or cessation of baby movements after you have started feeling them regularly, and a feeling that something is wrong, even if you cannot clearly describe the symptom. If you have symptoms that worry you, do not wait for the next scheduled appointment.
During the second-trimester check-up, blood pressure, body weight, uterine size, and the baby's heart rate are usually measured. The doctor may suggest additional blood and urine tests and a test for gestational diabetes, usually depending on the stage of pregnancy and personal risk factors. Regular check-ups are an opportunity to ask all your questions, from diet and exercise to travel, medications, preparation for childbirth, and breastfeeding.
