Your breasts change during pregnancy to prepare them for feeding your baby. These changes are caused by an increase in hormones, and may include the following:

  • Tenderness or a change in sensation of the nipple and breast
  • An increase in breast size
  • Changes in the colour and size of nipples and areola
  • Bigger and more noticeable Montgomery glands (small bumps on areola)

From about the 16th week of pregnancy the breasts are able to produce milk. It’s not unusual for small amounts of straw-coloured fluid called colostrum to leak from the nipples. If you’re worried that it may be noticeable on your clothes, you can use a breast pad (a disposable or washable fabric pad) inside your bra.

In the last few weeks of pregnancy the nipples become larger and the breasts continue to grow as the milk-producing cells get bigger. Your breasts may feel uncomfortable and sometimes painful. Wearing a well-fitting bra may help relieve any pain or discomfort. It’s fine to sleep in a bra if it’s more comfortable for you.

Women are usually advised to avoid certain types of pain relief while pregnant, but if your breasts are particularly painful you can talk to your GP or midwife for advice on pain medicate
