Week 7: 33 weeks to go!

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

Welcome back; you're now in week 7.

Your baby's progress:

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

Your progress: 

  • You may be concerned about having a miscarriage as 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.
  • Includes lots of fruit and vegetables to your diet.

Good to know:

  • Kegel exercises can help ease your delivery by strengthening your pelvic floor muscles. Start exercising now!
