5 weeks pregnant

What to expect this week

What's happening in week five

5 weeks pregnant

Five weeks in, and you might now be feeling quite a few of the signs of pregnancy!

At a glance

  • At five weeks gestation, they will be around 5mm long
  • Soon, your baby's heart will actually start beating
  • Try and relax, eat healthily and get plenty of rest

How big is my baby at five weeks?

Your little one is currently rocking an apple pip vibe in terms of size – but not for long!

At five weeks gestation, they will be around 5mm long, and their heart, brain and spine will be developing at a pace. Soon, your baby's heart will actually start beating, and if you have an early scan in the coming weeks, you would see it flickering on the monitor.

Your baby’s head is also seeing signs of development with the neural tube developing (the start of the connection between their spinal cord and brain) which will help to regulate your baby’s vital functions along with heart rate and blood supply.

Whilst your baby might currently resemble a tiny tadpole, their limbs are also starting to develop with nubs starting to turn into small limp flippers, the precursor to arms and legs forming.

You at five weeks pregnant

The signs of early pregnancy might have kicked in by now, but some women with an irregular cycle might still be in the dark as to what is causing the sickness, nausea, overwhelming tiredness and uncomfortable boobs! It will get better, so hang on in there!

If you know you are pregnant, you might be feeling a bit worried or anxious about how your pregnancy is progressing, particularly as you will not have had a scan or ante-natal checks at this stage. Try and relax, eat healthily and get plenty of rest, but do have a chat with your GP if you have any worries.

Some mums-to-be will spot or bleed early in pregnancy – have a read of our early pregnancy pages if you are concerned about this. Rarely, it could be a sign of ectopic pregnancy or miscarriage, so it is always best to get it checked out.

What to think about in week five

If you now know you are pregnant, you might be wondering if you can still safely exercise and continue to do all your usual activities. Keeping fit and active is really important in pregnancy, both for you and your baby's health, and potentially for an easier labour and delivery, too. If you currently regularly work out, unless it is something very high risk or a contact sport, you will be fine to continue at your own pace. It would also be wise to speak to your trainer or gym staff about how you should adapt your work out regime now you are expecting, just to be on the safe side.

Although you may not be ready to share your amazing news yet, you might be thinking about how and when you'd eventually like to share your pregnancy with your loved ones. Will you surprise them with a photo of your first scan? Or maybe you're thinking of dressing your fist in an, 'I'm the big sister' t-shirt for something extra adorable. Why not take a look at some more creative ways other people have announced their pregnancy for inspiration. You'll also be able to get a good idea on when your baby is likely to be due before your first scan by using our pregnancy due date calculator on Bounty.com.

At this early stage of pregnancy, eating a healthy, balanced diet is important but there are some specific nutritional tips and supplements that can help you have a healthy pregnancy. 

Folic acid is well known as a supplement to take when you plan to get pregnant and continue up until at least 12 weeks in to your pregnancy. It can help prevent birth defects such as spina bifida. Even if you have not taken folic acid up to this point, it’s never too late to start. 

Vitamin D is also really important in pregnancy as it can help regulate calcium and phosphate in your body to help teeth and bones stay strong.  

Iron tablets may also be advised if your blood tests from the midwife have shown your iron levels are low. Eating an iron rich diet can also help, with iron rich foods such as green leafy veg and dried fruit and nuts.

As well as eating the best foods for a healthy pregnancy, it’s just as important to steer clear of the foods that could adversely affect your pregnancy.

Reasons to avoid some foods is that they can carry bacteria which could cause listeria or salmonella. If contracted during your pregnancy, these could prove risky to you or your baby. 

Obvious examples are soft cheeses, especially mould ripened ones, but at this early stage of your pregnancy, you may find the smell (you may have previously loved) turns your stomach. Smells are a common cause of heaving in pregnancy and you may find, particularly in the early days, you develop some strong aversions to many everyday smells.
