How can I tell if there is a problem with my pregnancy?

Pregnancy is a time of great change for your body as you prepare for your baby to arrive. Sometimes, you may worry about some of the changes you are experiencing. It is a good idea to be familiar with common pregnancy health issues — you should also know when you should seek help. Some signs could point to a more serious pregnancy complication.

Some symptoms may happen at different stages of your pregnancy, while others could occur at any time. Even if you are not sure and think that something just 'doesn't feel right' with you or your baby's health, it’s best to get it checked by a health professional.

Call your doctor or midwife straight away if:

  • your baby is moving less than usual
  • you have experienced an injury to your abdomen
  • you have severe abdominal pain or bleeding from your vagina
  • you have blurred vision, sudden swelling or a bad headache that doesn't go away

The Symptom Checker guides you to the next appropriate healthcare steps, whether it’s self care, talking to a health professional, going to a hospital or calling triple zero (000).

Which symptoms should I get checked out?

Any time during pregnancy, contact your doctor, midwife or hospital immediately if you have:

Contact your doctor, midwife or hospital immediately if you’ve had a hit or blow to your stomach. This can include a fall, car accident or incident involving family violence.

See your doctor or midwife as soon as possible if you have:

  • problems with your emotional health that last longer than 2 weeks — such as feeling depressed or anxious, or being unable to do your usual everyday tasks
  • an unusual discharge from your vagina
  • weight loss
  • urgency, pain or a burning feeling when urinating (weeing)
  • swelling in your legs that doesn't improve overnight

Early pregnancy (before 20 weeks)

Contact your doctor, midwife or hospital immediately if you experience:

  • severe pain or cramping in your lower abdomen or pain in the tip of one shoulder — especially if you also have bleeding from your vagina
  • dizziness
  • fainting

Later pregnancy (after 20 weeks)

Contact your doctor, midwife or hospital immediately if you have:

  • changes to your vision, such as flashing lights or blurry eyesight
  • sudden, severe swelling in your hands, feet or face
  • a headache that doesn't get better if you take simple pain-relieving medicine
  • pain under your ribs
  • extreme itchiness of your skin, especially your hands and feet
  • swelling in your legs that doesn't improve overnight

Go to your local hospital immediately if your baby has stopped moving or is moving less than usual.

CHECK YOUR SYMPTOMS — Use the Symptom Checker and find out if you need to seek medical help.

What will happen when I see my doctor or midwife?

When you see your doctor or midwife, they will ask you about your symptoms and examine you. They may recommend some tests to check your and your baby's health. These tests may include:

They may give you a referral to another doctor or health professional, or they may suggest you go to hospital.

Your treatment will depend on your individual circumstances and the cause of your symptoms. Your health team may recommend more frequent health checks through your pregnancy. In some situations, your doctor or midwife will talk to you about if it's safest for your baby to be born early.
