Pregnancy at week 6

4-minute read

Your baby

This week your baby is growing very quickly – they will double in size to about 4mm long by the end of week 6.

By that time, the baby looks like a curved tadpole. It has a large head and a tail. Inside, the organs are starting to form. If you have an ultrasound in the sixth week, you may be able to see the baby’s heart beating.

The baby’s cells all have different jobs. They contain all the genetic information they needed to grow everything from the baby’s skin to their eyes to their liver.

Their jaw and eyes are starting to develop, as well as the ‘buds’ that will become arms and legs. Vertebrae are starting to form along their back. Also this week, a stalk which will develop into the umbilical cord attaches to the front of the baby’s body.

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.

You might also notice your sense of smell is stronger and you might be having dizzy spells.

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 the time to start eating healthily, which means eating all the nutrients you need for the baby and avoiding any foods that could harm them. It’s also important not to drink alcohol, smoke cigarettes or take illicit drugs while you’re pregnant since these can harm your baby.

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 help your body cope better with the demands of pregnancy.

Pregnancy hormone human chorionic gonadotrophin (hCG), the hormone a pregnancy test detects, is usually evident in the woman’s blood in the sixth week of pregnancy. Antenatal care should be provided at a doctor appointment for women who have not already checked their pregnancy health. Find out more about the pregnancy changes which occur this week.

2 weeks pregnant

When you are two weeks pregnant, your body is preparing for pregnancy but your egg has not yet been fertilised. Typically your egg will be released from your ovaries at the end of the second week of pregnancy and conception will occur on the first day of the third week of pregnancy. If you want to get pregnant, make sure you have plenty of sex this week so your partner’s sperm is ready and waiting to fertilise your egg.

1 week pregnant

The first week of pregnancy occurs before you actually conceive your new baby. It’s a little confusing - doctors begin counting the weeks of your pregnancy from the date your last menstrual bleeding started, not from the date you conceived. Conception, that very important moment at which your partner’s sperm fertilises your egg, does not occur until approximately two weeks after the start of your last period. However, your body is already preparing itself for pregnancy, should conception occur, so this week officially marks the beginning of the pregnancy.
