Week 8–9 marks an important milestone: the embryo is now officially called a fetus. This means the major organs have started forming, even though they are still immature. The fetus is now about 15–25 millimeters long – approximately the size of a raspberry or cherry. Despite its tiny size, the beginnings of arms, legs, fingers, and toes are visible – at first webbed, but that will soon change.

The brain is developing rapidly and begins to divide into different regions responsible for movement, emotions, and sensory input. The heartbeat becomes stronger and more regular, and in some cases, it may be possible to hear it with a vaginal ultrasound. Muscles are forming, and although you cannot feel any movement yet, the fetus is actually starting to make tiny spontaneous movements.

Facial features are becoming more defined – eyelids are forming, the nose becomes visible, and the ears move into the correct position on the head. The lungs begin their early development, and the stomach, kidneys, and intestines are forming their initial structures, although they are not functioning yet.

For the pregnant person, hormone levels – especially hCG – may peak at this time. This is why nausea, fatigue, and emotional sensitivity may feel stronger now. Many describe being more sensitive to smells or experiencing sudden mood shifts. This is the body’s natural way of protecting the pregnancy and signaling the need for rest and energy.

Alma’s tips 🌿

• Continue taking folic acid (recommended until week 12 by CDC/WHO).

• If nausea is tough, try ginger, oat biscuits, or eating before getting out of bed.

• Emotional ups and downs are completely normal. You don’t have to feel happy all the time.

• You might hear the heartbeat now – but don’t worry if it’s too early.
