• Health Monitoring: Understand what to expect in each trimester and address concerns early
• Emotional Readiness: Stay informed about your baby’s development to feel more connected and prepared
• Support System: Share key dates with family and healthcare providers for better support

The Stages of Pregnancy

First Trimester (Weeks 1-12)

The first trimester starts from the first day of your LMP and lasts until the end of week 12.

• Baby’s Development: Major organs and systems form, heartbeat begins, and limbs develop.
• Your Body: You may experience fatigue, nausea, breast tenderness, and frequent urination.
• Tips: Start prenatal vitamins, eat a balanced diet, stay hydrated, and avoid alcohol and smoking.

Second Trimester (Weeks 13-26)

The second trimester is often called the "honeymoon phase" as many women feel more energetic.

• Baby’s Development: Baby grows rapidly, starts moving (you may feel kicks), and develops facial features.
• Your Body: Your bump becomes noticeable, energy levels may improve, and you might experience heartburn or back pain.
• Tips: Engage in light exercise (e.g., walking, prenatal yoga), monitor weight gain, and attend regular checkups.

Third Trimester (Weeks 27-40)

The third trimester prepares you and your baby for delivery.

• Baby’s Development: Baby gains weight, lungs mature, and prepares for birth (head-down position).
• Your Body: You may feel more tired, experience swelling, Braxton Hicks contractions, and shortness of breath.
• Tips: Rest frequently, practice breathing exercises, pack your hospital bag, and discuss your birth plan with your doctor.

Tips for a Healthy Pregnancy
