25 Weeks Pregnant: Baby Development, Symptoms & Tips for Moms-to-Be

Dear Mom-to-Be, as you move closer to your due date, pregnancy can start to feel a little overwhelming—especially when you find yourself imagining what your baby might look like. Congratulations! At 25 weeks, your baby is more aware of their surroundings. At this stage, your baby can react to light, touch, and sound.In this blog, let us explore the key developments happening with your baby and the changes you may notice in your body during week 25.

Baby Development At 25 Weeks

At 25 weeks pregnant, your baby is now around 34.6 cm in length (from head to toe) and weighs approximately 0.7 to 0.8 kg. This week, your baby may appear less wrinkled as fat begins to develop under the skin, giving a fuller appearance.

At this stage, your baby also starts excreting waste into the amniotic fluid, which plays an important role in maintaining a stable temperature around your baby.

You may now feel stronger movements, such as jumps and kicks. Interestingly, your baby can respond to external sounds and light from the outside world! Hiccups may also begin around this time—when they occur, you might feel gentle, rhythmic jerks, which are completely normal and nothing to worry about.

It’s important to monitor your baby’s movements regularly. If you notice a significant slowdown or absence of movement, please consult your doctor immediately.

25 weeks pregnant is how many months?

25 weeks pregnant is equal to 6 months. Pregnancy is typically measured in weeks, and week 25 falls within the sixth month. At this stage, you're in the second trimester, with about 15 weeks left until your due date.

Few Common Concerns At 25 Weeks Pregnant

Growing Bump

As your pregnancy progresses, both your baby and bump continue to grow, and you may start to feel noticeably bigger. This is completely normal—your baby is developing rapidly, and your body is adapting to support that growth. You might also notice changes in your breast size and an increase in blood volume.

Don’t stress about the numbers on the scale. Instead, focus on maintaining a healthy, balanced diet that nourishes both you and your baby.

Stomach Pain

As your baby grows, your stomach expands, and the muscles and ligaments stretch to accommodate your developing baby. These changes can lead to mild stomach pain or discomfort, which is quite common during pregnancy.

Piles (Haemorrhoids)

Piles are another common concern during pregnancy. They occur due to the enlargement of blood vessels around the rectal area, often caused by increased pressure and hormonal changes. Staying hydrated and eating a fibre-rich diet can help prevent or ease discomfort.

Disturbed Sleep Patterns

You may find it increasingly difficult to sleep comfortably, especially as your bump grows. Using supportive pillows around your belly and between your knees can help improve sleep quality.

Caution

Avoid sleeping on your back, especially after 28 weeks of pregnancy. This position can restrict blood flow and has been associated with an increased risk of stillbirth. Try to sleep on your side, preferably the left side, for better circulation and safety.

Scans & Tests At 25 Weeks Pregnant

By 25 weeks of pregnancy, most of the major genetic screening tests—such as NIPT (Non-Invasive Prenatal Testing), Chorionic Villus Sampling (CVS), and Amniocentesis—are usually completed earlier in the pregnancy. Here's a quick recap and what you might expect now:

NIPT: A simple blood test done as early as 9 weeks to detect the baby’s gender and risk of chromosomal conditions (e.g., Down syndrome). It’s typically recommended for high-risk pregnancies.
Chorionic Villus Sampling (CVS): Usually performed between 8–10 weeks, it involves testing placental tissue for genetic abnormalities. It carries a small risk of miscarriage.
Amniocentesis: Usually done between 15–20 weeks, this test analyses the amniotic fluid for chromosomal and genetic conditions. It also carries a small risk and is used selectively.

When To Call A Doctor?

It’s important to listen to your body and contact your healthcare provider if you notice any of the following signs:

• Bleeding or spotting
• Regular cramping that could indicate preterm labour
• Unusual vaginal discharge – especially if it's watery, green, yellow, or has a strong odour
• Lower back pain that feels persistent or sharp
• Pain or burning while urinating, which could signal a urinary tract infection
• Severe pain or pain that doesn't improve even after resting for 30 to 60 minutes

Conclusion:

At 25 weeks, you’re well into your second trimester, and your baby is growing stronger, more active, and increasingly responsive to the world around them. While your body is going through many changes—some exciting and some uncomfortable—it’s all part of the incredible journey of bringing new life into the world.

Stay mindful of your baby’s movements, nourish yourself with a healthy diet; and prioritise rest and emotional well-being. Remember, not every symptom is a cause for concern, but always trust your instincts and don’t hesitate to reach out to your healthcare provider if something doesn’t feel right.

You’re doing an amazing job, Mama—every little kick is a reminder that you’re getting closer to meeting your baby. Keep going, and take one week at a time.

At 25 weeks, your baby is about 34.6 cm long (from head to toe) and weighs approximately 0.7 to 0.8 kilograms—about the size of a cauliflower! Your baby is growing quickly and starting to gain more fat, which smooths out their skin.

Q3) Do you feel foetal movements when you're 25 weeks pregnant?

Yes, you are likely feeling more noticeable kicks, rolls, and jabs at this stage. Your baby is becoming more active and responsive to sounds and light. If you feel fewer movements than usual, it’s best to contact your doctor for guidance.
