Pregnancy at week 6

5-minute read

Your baby

This week your baby is growing very quickly. They will double in size and look more like a tadpole - with a large head and a tail.

Inside, their organs are starting to form. Your baby’s cells all have different jobs. They contain the genetic information they needed to grow everything from their skin, to their eyes, to their liver.

Their jaw and eyes are starting to develop now, as well as the ‘buds’ that will become arms and legs. Vertebrae are also starting to form along their back.

If you have an ultrasound in the sixth week, you may be able to see your baby’s heart beating.

Your body

If you didn’t realise you were pregnant last week, you will probably have noticed a missed period by now. You may also be feeling tired, your breasts may be tender, and you may be feeling nauseous or even vomiting.

Not all women experience morning sickness during pregnancy. It can happen at any time of day, not just in the morning, but it usually clears up by about 3 months into pregnancy. If you’re feeling very unwell or you have severe vomiting that doesn’t stop, talk to your doctor or midwife.

Things to remember

It’s a good idea to start your pregnancy care as soon as you realise you’re pregnant. See your doctor, who will confirm the pregnancy with a blood test, talk to you about your care options, and give you advice on how to look after yourself and your baby.

Make sure you tell your doctor if you are taking any medications. Now is also the time to start eating healthily, which can be easier said than done, particularly if you’re feeling nauseous. Try to eat small frequent meals and avoid foods that could be harmful during pregnancy.

If you’re feeling sick and tired, some gentle exercise may help you to feel better. Swimming or walking are good options. Keeping fit will also help your body cope with the demands of pregnancy.

Resources and support

Speak to your doctor, midwife or obstetrician if you have questions about your pregnancy.
