Pregnancy Week By Week

19 Weeks Pregnant: Development, Symptoms and Care

At 19 weeks pregnant, you may be getting used to a changing shape and wondering whether a small flutter really was your baby. You may also be preparing for an anatomy scan. There is no particular bump size or emotional response you are supposed to have at this point.

Your baby’s development at 19 weeks

A creamy coating called vernix is developing over your baby’s skin, helping protect it in the amniotic fluid. Brown fat is also building beneath the skin; this type of fat helps with warmth. These are changes around this stage of development, not measurements you need to track at home.

Body changes and symptoms

Breasts and feet may feel bigger, and clothes or shoes that fitted a few weeks ago may no longer be comfortable. Supportive footwear and a well-fitting bra can be more useful than trying to fit a particular maternity size.

Heartburn can also be bothersome during pregnancy. Try smaller meals, eat slowly and avoid lying down straight after eating. If symptoms are affecting meals or sleep, ask a pharmacist or your clinician about suitable treatment rather than assuming you have to put up with them.

First movements and your own pregnancy

Most people start to feel their baby between 16 and 24 weeks. A first pregnancy may take longer to recognise than a later one. Early sensations can be gentle flutters rather than obvious kicks.

If movements reduce, change in a way that worries you or simply do not feel right, contact your midwife, doctor or maternity unit immediately. Do not wait for a certain number of kicks or for tomorrow. If you have never felt movement by 24 weeks, contact your care team; any concern before then also deserves advice.

The morphology scan

The anatomy, or morphology, scan is usually offered around 18 to 22 weeks. It looks at the baby’s body and organs and the position of the placenta. Your service may recommend a particular week within that window.

The scan cannot find every condition. You can ask what it is checking, what its limitations are and how the results will be explained. Tell the sonographer whether you want to know the baby’s sex, while understanding that it may not be possible to tell. Having the scan is your choice. Our prenatal tests guide can help you prepare.

A practical step this week

Check that you know the scan location, any preparation, possible costs and whom to call if the appointment cannot go ahead. If you would like company, ask about bringing a support person.

Comments about your bump can be tiring. You can keep the conversation brief or tell people you would rather discuss something else. Bring concerns about growth to your clinician, who can assess your pregnancy instead of judging it by appearance.

When to seek medical help

In Australia, call 000 for heavy bleeding, severe abdominal pain, severe breathing difficulty, chest pain or collapse. Do not drive yourself if faint or very unwell.

Contact your GP, midwife or hospital immediately for vaginal bleeding, leaking fluid, fever, vomiting that prevents drinking, persistent or worsening pain, or concerning contractions. Severe headache, blurred vision, sudden swelling or pain under your ribs also needs urgent assessment. If your usual team is unavailable, seek urgent care rather than waiting for an appointment.
