The baby already weighs around 600 grams and it will become four to give times heavier before it is born.
It now carries out complex series of movements. The baby has a sense of balance and can orient itself inside the womb. You will be able to see your stomach moving as the baby twists and turns.
From now on, your doctor will check the haemoglobin in your blood more frequently. If it is too low, you might have an iron deficiency and your baby will not be receiving the ideal amount of oxygen. If that is the case, your doctor will prescribe you an iron supplement.
At this stage in the pregnancy, the hormonal changes happening in your body often start to have positive effects. Your skin might become clearer and smoother, your hair shinier and your fingernails stronger than they were a few weeks ago.
During weeks 20 to 24 of pregnancy your baby is about the size of a papaya.
