In the week 12, your baby is
the size of an Lime
In Week 12 of pregnancy, your baby’s development leaps forward! Expect more noticeable changes, new symptoms, and exciting milestones as you enter the second trimester.
Welcome to Week 12 of pregnancy! Congratulations—you've made it through the first trimester! Many women experience less nausea and fatigue, and look forward to increased energy. Your baby is growing rapidly, and as your body adjusts, you can expect positive changes in the weeks ahead.
At Week 12, many women experience a reduction in the intensity of early pregnancy symptoms. However, there are still a few things to be aware of:
At the twelfth week of pregnancy, your baby is roughly the size of a lime. This week marks significant progress as your baby’s body continues to develop and take shape.
Organ Development: By Week 12, your baby’s major organs, including the heart, liver, and kidneys, are fully formed. The digestive system is active, and the kidneys are producing urine, which is excreted as amniotic fluid.
Physical Features: Your baby’s facial features are becoming clearer, with fully developed eyes (still closed), and the nose, ears, and mouth are taking shape. Tiny fingernails and toenails are forming.
Weight of the Foetus: At Week 12, your baby measures 2.13 inches (5.4 cm) and weighs about 14 grams. They are growing quickly and preparing for more rapid development in the second trimester.
Movement of the Baby: Your baby is moving their arms and legs, practising muscle tone and coordination. These movements are too subtle to be felt yet.
At 12 weeks, you’re starting a new chapter! Take care of yourself and embrace the amazing journey ahead.
At Week 12, your body adapts to pregnancy with changes in breasts, skin, and energy levels as you enter the second trimester.
Childbirth prep
Enrol yourself in prenatal courses to learn different labour stages and what to expect.
Take Prenatal Vitamins
Ensure you take prenatal vitamins throughout your pregnancy and the postpartum period
Early arrival
Discuss premature labour signs with the doctor to address concerns and get proper guidance.
Preterm signs
If you suspect early labour, read up on premature delivery and baby care essentials.
Dental hygiene
Having healthy teeth and gums matters as poor dental care is linked to premature labour.
In Week 12, routine screenings and tests help assess both your health and your baby’s development, ensuring everything is on track.
At this stage, the combined test for Down syndrome includes a blood test and ultrasound to measure nuchal translucency (fluid at the back of the baby’s neck). This is sometimes called a nuchal translucency scan.
A standard ultrasound checks your baby’s development at 12 weeks. Additional scans may be recommended if concerns arise, such as investigating symptoms like bleeding.
Routine blood tests check for conditions like anaemia or infections to ensure both your health and the baby’s wellbeing.
Your doctor will monitor your weight and blood pressure during routine prenatal visits to ensure healthy progress throughout your pregnancy.
Your baby is about the size of a lime, measuring around 2.13 inches long and weighing about 14 grams.
Yes, some fatigue is still common, but many women experience a surge in energy as they enter the second trimester.
Light exercises like walking or prenatal yoga are safe. Always check with your doctor before starting any new exercise routine.
You may be able to see your baby’s heartbeat and movements, and your doctor will check the development of your baby’s organs.
Travel is generally safe during the second trimester, but always consult your healthcare provider, especially if you have a high-risk pregnancy.
Focus on a nutrient-dense diet with plenty of folic acid, protein, healthy fats, and calcium-rich foods. Keep your meals balanced and varied.
Eat well, stay hydrated, and continue with any recommended supplements. Regular check-ups and gentle exercise will also help you maintain a healthy pregnancy.
At the twelfth week, the ultrasound is usually part of a combined screening test. During the scan, your healthcare provider will check your baby's size, measure nuchal translucency (fluid at the back of the baby’s neck), and confirm the pregnancy’s progress. You may see your baby’s head, body, and limbs on the screen, and you might even catch a glimpse of their tiny movements.
