What is happening to your baby:

  • The baby is about 2cm long (the size of a small bean) and weighs about 1 gram.
  • The face changes almost daily. Dark spots appear where the eyes and nostrils will be and indentations for the ears.
  • Buds that will become the arms and legs are more noticeable.
  • The internal organs – the lungs, digestive system and excretory system – form.
  • Growth of the pituitary gland and muscle fibres.
  • Pancreas and bronchi grow.
  • Heart has divided into chambers.
  • The testes or ovaries have formed.

The embryo makes its first movements but you won’t be able to feel them at this stage.

Miscarriages are usually caused by inadequate development of the placenta, the umbilical cord and/or the embryo. Poor health and nutrition of the mother or the intake of toxic substances may also lead to a miscarriage.

What to do:

  • Discuss your concerns about miscarriage with your doctor.
  • Make sure that you eat correctly.
