You and your baby's development

What's happening in week 6 of your pregnancy

6 weeks pregnant and the changes in your growing baby (and your body) continue big time

  • Now is the time to really watch your diet
6 Weeks pregnant

How big is my baby at 6 weeks?

If you can imagine a tiny poppy seed, that’s the size of your growing baby's heart now. Their heart is also changing from being a simple, single tube to a complex four chamber organ which will pump blood around their body. How amazing! All your baby's other vital organs – the kidneys, lungs and liver – are now in place too, but they still have a lot of developing left to do. The little buds which will eventually become their arms and legs are also starting to develop. 

Facts to know about your baby in week 6

  • Your baby is the size of a pomegranate seed
  • From conception to birth, a baby's weight increases 3,000 million times
  • Your baby is now about 1 cm in size and not much bigger than a little bean
  • Your baby has tiny 'arm buds' which look like paddles
  • Your baby's brain waves are strong enough to be recorded

You at 6 weeks pregnant

You might be feeling a touch 'hormonal' by week six, and your morning sickness, tiredness and general feelings of exhaustion might have really kicked in.  Now is the time to really watch your diet – not only to give you nutritious, energy giving foods, but also to make sure you are avoiding anything that could be harmful to your baby. Check out our diet and health in pregnancy pages for ideas for healthy meals and which foods to give a wide berth at this stage.

Getting lots of fresh air will also be of huge benefit to you and your baby as your pregnancy progresses – our bodies can only produce vitamin D when exposed to sunlight, so try and get out and about in the sun as much as possible.

Oh, and there's just over seven months left to go!

Facts to know about you in week 6

  • During pregnancy, your sense of smell increases drastically, as does your sense of taste
  • Pica is a recognised condition where pregnant women crave non-foods like chalk and charcoal

What to think about in week 6

You might be giving off a few signs of pregnancy to other people now, particularly if you are steering clear of the office coffee machine and its overwhelming aromas, or making lots of visits to the bathroom if you are feeling sick or needing to wee a lot (or just for some breathing space if you are feeling mega tired!). Most women wait for their dating scan to share their good news with their friends and colleagues, so you might have to keep up an 'upset tummy' or 'ate something dodgy' line for a while! Could be time to think about how you'll make your exciting announcement though – sharing your scan pic on social media, or just spreading the word via good old fashioned face to face communication?

Signs and symptoms at 6 weeks pregnant

Morning sickness

It may be called ‘morning’ sickness but if you’ve got it bad you’ll already know it can affect you throughout the day. Morning sickness usually starts around week 6 of pregnancy and will last until around week 14. Caused by hormonal changes, morning sickness is no fun, but it shouldn't affect your general health or your baby in any way. Luckily, your body has good stores of essential nutrients to draw on. However, if you’re being sick a lot, you may have severe morning sickness (hyperemis gravidarum) which, in severe cases, can be eased with anti-sickness medication. It’s important to get help, because it can make you very ill and severely dehydrated.

Peeing more often

Another symptom that you may not be expecting so early in your pregnancy is needing to pee more often, but actually it’s a common early sign. Shortly after you become pregnant, hormonal changes cause blood to flow more quickly through your kidneys, filling your bladder more often. Even in the first trimester, your uterus puts pressure on your bladder, giving it less room to store urine. Luckily this pressure eases as your pregnancy progresses.

Thinking about your finances?

It’s natural to turn your attention to your finances soon after the excitement of discovering that you’re pregnant. Now is a good time to check what you’re spending and for some couples, it may be the first time you have had to seriously talk about money. Take a look at the money you have coming in now (remembering that income drops when you are on maternity leave) and your outgoings. Think about whether there is anything you can cut back on. Are there subscriptions you could cancel, or spending habits you could break?

An online budget tool will help. It may also be sensible doing two budgets – one for now, and one for when you are on maternity leave to allow for drops in income and additional expenses.
