At 14 weeks, the baby is about 85mm long from head to bottom.
Around now, the baby begins to swallow little bits of amniotic fluid, which pass into the stomach. The kidneys start to work and the swallowed fluid passes back into the amniotic fluid as urine.
If you've been feeling sick and tired with morning sickness, you'll probably start to feel better when you're around 13 or 14 weeks pregnant.

See your doctor if you notice any pain when you urinate. Urinary infections can happen in pregnancy and it's important to treat them quickly to reduce the risk of kidney infections.
