It's important to eat a healthy, balanced diet and do some physical activity every day. You should be offered a referral to a dietitian or other health professional for advice on healthy eating and physical activity. Being physically active in pregnancy will not harm your baby.

Try eating healthily (including knowing what foods to avoid in pregnancy) and doing activities such as walking or swimming.
If you were not active before pregnancy, it's a good idea to consult your midwife or doctor before starting a new exercise plan when you're pregnant.
