Warning signs during pregnancy

3-minute read

Pregnancy is a time of great change for your body, and in your life, as you get ready for your baby to arrive. It also can be a time when you may be worried about some of the changes you are experiencing, and you want to know when you should seek help.

Most changes in your body are likely to be a normal part of pregnancy and a majority of pregnancy health issues are mild and common. However, there are some signs that can indicate that things may not be going well, and these could signal a more serious pregnancy complication.

Some of these symptoms may appear at different stages of your pregnancy; others might occur at any time. Even if you are not sure about your symptoms but think that something just doesn't feel right with your own or your baby's health, it's important to get it checked out.

Contact your doctor, midwife or hospital immediately if you have any of the following symptoms:

Any time during pregnancy

While some signs may only appear at certain times during your pregnancy, many can occur at any stage, including:

  • prolonged or severe vomiting
  • bleeding from your vagina
  • a discharge from your vagina that is unusual, or a lot more than usual
  • have very bad or long-lasting headaches
  • dizziness
  • continuing weight loss
  • fever or chills
  • urgency, pain or a burning feeling when urinating (weeing)
  • feeling constantly out of breath, dizzy or weak or having a racing heart
  • you have had a blow to your stomach (e.g. from a fall, crash or from a family violence incident)
  • you are experiencing problems with your emotional health that last longer than 2 weeks, such as feeling depressed, anxious or being unable to do your usual, everyday tasks

Early pregnancy (before 20 weeks)

Certain types of pain in the early stages of pregnancy could be a sign of miscarriage or an ectopic pregnancy:

Later pregnancy (after 20 weeks)

Although some discomfort is common during the later stages of pregnancy, there are some signs that need to be checked by a doctor immediately, including:

What happens next?

When you see your healthcare professional they may perform some tests to check or maintain the health of you and your baby. These tests may include:

You may also receive a referral to another doctor or specialist, and you can also get emotional support.

How can I avoid pregnancy complications?

It's often not possible to avoid a complication in pregnancy. You may have a higher chance of developing one if you have a health problem now, or had one during a previous pregnancy. There may also be a higher chance if you have a family history of a complications which can occur in pregnancy.

It may be possible to lessen the chance of developing a problem, or for it to become worse, by making sure you go to all of your antenatal appointments. If a potential health issue is found, you may need additional antenatal appointments in order to more closely monitor the health of you and your baby.

Where to get help

  • Phone your doctor, midwife or maternity hospital urgently if you have any concerns.
  • Visit your hospital or call triple zero (000) and ask for an ambulance.
