6 Weeks Pregnant | Symptoms and What To Expect

6 Weeks Pregnant

At 6 weeks pregnant, you may notice that you need to pee more often — especially in the middle of the night!

This will ease in the coming weeks, only to return with a vengeance later in your pregnancy.

You will also be feeling a little more fatigued than normal.

Your body is making a baby, which is a mammoth effort.

Make sure you don’t push yourself – listen to your body when it’s telling you to rest.

There’s a very good chance that morning sickness has paid you a visit — it affects around 80-90% of pregnant women.

Don’t get mislead by the name, ‘morning sickness’, because it often lasts all day. No one is sure what causes morning sickness, but it’s suspected that the significantly rising levels of hCG (human chorionic gonadotrophin, the pregnancy hormone) play a major part.

Some unlucky pregnant women will develop hyperemesis gravidarum, which is severe morning sickness. Hyperemesis gravidarum often means a short stay in hospital for rehydration, and requires some practical and emotional support for mum-to-be. For more information, read our article, here.

6 Weeks Pregnant – Your Baby

Your baby already has a bloodstream. It’s heart, which is no bigger than a poppy seed, has started to beat and pump. The heart is not yet fully formed — it only has two chambers instead of the usual four. But this will soon develop. The baby’s heart beats at around 150bpm (beats per minute) which is around twice the rate of an adult!

If you could look closely, you would see four little buds, which will soon become arms and legs. On the sides of your baby’s head, eyes have started to develop. Over the following weeks, the eyes will move into the correct position. The lungs are just starting to appear, along with the kidneys and intestines. Your baby’s spine has started to form.

At 6 weeks pregnant, your baby starts to look a little like a jellybean and is about 4-5mm long – the size of a grain of rice! Babies at this age are measured from crown to rump (i.e. head to bottom), so the measurement excludes his or her legs.
