Week 8 

Now, the fetus is about 16mm. The arms of the fetus are already getting longer and bigger than the legs because the upper part of the body grows faster than the lower part. 

Ankles, knees, fingers and thighs have not yet developed in the legs. At this stage, many body systems and organs and major body systems have begun to form. It includes the brain, heart, liver, nervous system, kidneys and intestines. 

The amniotic sac, which is filled with amniotic fluid, also helps protect the baby and acts like a ‘cushion’ by absorbing any external pressure or impact. 

Symptoms 

You may feel tired and listless. Even some pregnant women find they urinate more often. It happens when your expanding uterus presses on your bladder. 

Tips for you 

If you find yourself urinating frequently, and it’s affecting your sleep, try drinking plenty of fluids during the day but less at night.
