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 symptoms - what's happening

Pregnancy tiredness and morning sickness in the first trimester can really knock you. Put up your feet and read our tips to help you get through the day.

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).

Constantly needing a wee?

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?

That’ll be the hormones making your gums inflamed. You need to take extra care of your pearly whites and make sure you 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).

Actions to take

Exercise... are you kidding?

There’s nothing quite like pregnancy tiredness. It can feel like you’re drudging through thick fog and be utterly debilitating.
It might sound bonkers but the best antidote to tiredness can be exercise. Don’t worry about being active while you’re pregnant - it’s great for both you and your baby (unless your doc tells you otherwise).

“I was so excited to be pregnant, but it also made me feel very tired. I could have slept all day and then still be tired when I woke up. It’s an exhaustion like nothing you've ever felt before.”
Louisa, mum of two
