Halfway Milestone: Celebrating Pregnancy Progress

Congratulations on reaching the halfway point of your pregnancy! Your baby is now stretching and flexing, growing bigger and stronger with each passing day. Let’s explore what this significant milestone entails.

Baby’s Development: Heightened Awareness and Protection

At approximately 22cm in length, your baby’s awareness is increasing as their brain continues to develop, particularly the part responsible for controlling their senses. The heartbeat is now strong and easily detectable, indicating healthy growth. Additionally, the skin is secreting vernix, a thick white mucus serving as a protective waterproof barrier in the womb.

Anticipating the 20-Week Scan: Ensuring Normal Development

You’re scheduled for the 20-week anomaly scan, a crucial examination to ensure your baby’s development is on track. This scan provides a comprehensive assessment of your baby’s physical growth and checks for any abnormalities. It’s also an exciting opportunity for you to catch a glimpse of your growing baby and share the joy with your partner or friend.

Understanding the Scan Process: Exploring Baby’s Details

During the 15-20 minute scan, the sonographer meticulously examines your baby’s growth and development, including the position of the placenta. You may even get to see your baby on the screen and learn details such as their heartbeat and growing limbs. While not all hospitals disclose the baby’s sex during this scan, you can always inquire if you wish to know.

Managing Leg Cramps: Common Pregnancy Symptoms

Leg cramps are a common discomfort during the second and third trimesters. These cramps may result from the extra weight you’re carrying, calcium or salt deficiency, dehydration, prolonged inactivity, or pressure on nerves due to your growing bump. If you experience concerns about leg cramps, don’t hesitate to consult your doctor for guidance and support.
