Before you get pregnant you can calculate your BMI. But this may not be accurate once you're pregnant, so consult your midwife or doctor.
Having a healthy diet and doing moderate exercise are advised in pregnancy, and it's important not to gain too much weight.
Foodwise can also assist in eating a balanced diet. If you want to speak to a health professional about this, please chat to your doctor, or you can click here to visit the weight management service where you can self-refer (opens in new tab).
