7 weeks pregnant – all you need to know

Your baby, who was once the size of bean, is now the size of a grape.

Week 7 infographic.

What does my baby look like? 

Your baby starts to take on slightly alien-like qualities as their head grows faster than the rest of their body. This is to make room for their rapidly developing brain.

Cartilage starts to form in their teeny arm and leg buds. The arms grow longer and flatten out at the ends. This is the beginning of tiny hands.

A delicate network of nerves is spreading through your baby’s body. They are going to start making constant little motions, as their brain and spinal cord sends signals to the muscles in their body. Soon your baby will be able to feel sensations, like temperature and taste.

Your pregnancy symptoms in week 7

Feeling thirsty?

The volume of blood in your body is increasing and this can make you feel thirstier than usual. Aim to drink eight medium glasses of fluid a day (sip if you are feeling sick).

Needing to pee more than usual?

You may notice that you need to wee more often. This often starts in early pregnancy thanks to hormones and continues as your growing womb presses on your bladder.

Are your gums bleeding when you brush your teeth?

The hormones make your gums inflamed. You need to take extra care of your teeth. Book an appointment with your dentist, which is free during pregnancy. 

Find out more about how to care for your teeth and gums in  10 common pregnancy complaints (and how to avoid them).

What to do in week 7

Taking steps to having a healthy lifestyle will make a huge difference to yourself and your baby.

Staying active is safe and healthy

Staying active while you’re pregnant is great for both you and your baby. It can help with the tiredness and has a host of other benefits.

The amount of exercise you can do during pregnancy will depend on how active you were before you got pregnant.

Even if you previously did no exercise, it’s important to start being active now for a healthy pregnancy. Being sedentary (sitting down a lot) has been shown to increase risks during pregnancy. There are lots of different things you can do to start being more active in your everyday life. Our 10 tips for staying active in pregnancy is a good place to start.
