Prenatal Care: What to Expect During Your First Trimester

The first trimester of pregnancy is a crucial time for both mother and baby. As a gynecologist specializing in prenatal care at Muhimbili National Hospital, I guide many women through this exciting journey. Here's what you can expect during your first trimester.

First Trimester Timeline

Weeks 1-4: Early Development

During these early weeks, you may not even know you're pregnant yet. However, important developments are occurring:

• Fertilization and implantation
• Formation of the neural tube
• Development of the placenta

Weeks 5-8: Major Organ Development

This is a critical period for organ development:

• Heart begins beating
• Brain and spinal cord develop
• Arms and legs start forming
• Facial features begin to appear

Weeks 9-12: Rapid Growth

By the end of the first trimester:

• All major organs are formed
• Baby begins to move (though you won't feel it yet)
• Risk of miscarriage significantly decreases

Common First Trimester Symptoms

Morning Sickness

Nausea and vomiting are common, especially in the morning. Tips to manage:

• Eat small, frequent meals
• Avoid strong odors
• Stay hydrated
• Consider ginger supplements

Fatigue

Extreme tiredness is normal due to hormonal changes. Rest when possible and maintain a healthy diet.

Breast Changes

Your breasts may become tender and swollen as they prepare for breastfeeding.
