We look at your baby's development and the risk of miscarriage in the first trimester.


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.

What is happening to you:
You may be concerned about having a miscarriageas this can easily happen during the embryonic period. 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.
