5 weeks and 6 days pregnant

Development in the upper body usually precedes that in the lower body – this image shows the bulge containing the heart and liver, and the very earliest sign of development of the upper limb buds, but as yet there is no sign of the lower limb buds.

The first change in body shape you may notice is a marked increase in your breast size, even at this early stage of pregnancy.

The first part of your body to change shape is likely to be your chest. Your breasts may increase in size quite rapidly, looking bigger and feeling heavier. They may also become quite tender to touch.

The nipples will change: the areola (the darker skin around the nipple) may become darker in colour and your nipples may tingle. As your breasts get bigger, you might notice blue veins appearing. All these breast changes are due to the hormone oestrogen.

Each breast will increase, on average, by 5cm (2in) and 1.4kg (3lb) during pregnancy.

That is why it is important to wear the right bra, even in the early stages of pregnancy.

How can I ease the soreness in my breasts?

Wearing a supportive bra can help with both the feelings of heaviness and the soreness in your breasts, which are common in pregnancy. If your breasts are very tender at night, try wearing your bra during the night while you sleep as this may help. Try to avoid sleeping on your front if this causes discomfort. You may find that rubbing in a cream containing aloe vera or camomile is soothing.

Once you know you’re pregnant, it’s only natural to want to keep your baby safe, so...

Take care when you’re cleaning.Studies suggest there may be a link between pregnant women using bleach and spray air fresheners, and babies developing asthma. Plus, commercial oven cleaners contain toxic chemicals that experts believe could damage unborn babies.

• Don’t use “toxic” products.

• Keep rooms well ventilated.

• Steer clear of fumes.

• Wear gloves.

• Make your home sparkle with a solution made of bicarbonate of soda, distilled white vinegar, lemon juice, and essential oils.

Get someone else to clean your cat’s litter tray (or if that’s not possible, wear rubber gloves and wash your hands afterwards). Cat faeces may contain parasites that can cause toxoplasmosis, an infection that could harm your unborn baby.

Read the labels on cleaning products carefully to make sure they are not toxic, and always wear rubber gloves. Pregnancy can be a good time to ask your partner to clean the bathroom!
