The first trimester

The first trimester (weeks 1-12) is a period of rapid development where a fertilized egg becomes an embryo, forming vital organs and features, while the pregnant person experiences significant hormonal shifts causing symptoms like fatigue, nausea (morning sickness), mood swings, and breast tenderness, with a missed period often being the first sign, requiring early doctor visits for essential care like folic acid and scans.

Key Developments
Fetal Growth: From a cell cluster to a tiny human with formed organs, bones, muscles, and a heartbeat by week 12, growing faster than any other time.

Organ Formation: By week 5, all building blocks for vital organs are in place, with rapid brain and spinal cord development.

Placenta & Cord: The umbilical cord and placenta form to provide oxygen and nutrients.

Common Symptoms (Due to Hormones)
Extreme tiredness & fatigue
Nausea & vomiting (morning sickness)
Sore or tender breasts
Frequent urination
Mood swings
Food cravings or aversions
Light spotting or cramping (usually normal)

What to Do
See Your Doctor: Book an appointment ASAP to confirm pregnancy and discuss care, starting folic acid and getting recommended vaccines (Flu, Whooping Cough, COVID-19).

Eat Well: Small, frequent meals, iron-rich foods, plenty of water.

Rest: Go to bed earlier and rest when you can.
Gentle Exercise: Can boost energy.

Avoid Harm: Stay away from alcohol, drugs, and certain medicines, as the fetus is very vulnerable.
