Your baby

Your baby is gaining fat while organs continue to mature. The fine hair and protective coating on the skin are changing as pregnancy progresses. These changes unfold over several weeks, rather than finishing all at once. The butternut-squash comparison is an approximate guide to size, not a countdown to a particular birth date.

Your body

Bathroom trips, leg cramps or discomfort may interrupt sleep. You may also find yourself thinking more about labor and delivery. It is possible to feel both prepared and uncertain. If worry makes it hard to rest or function, bring that up as part of your care rather than treating preparation as a task you must complete alone.

Talking through birth preferences

Start with two or three things that matter most to you about the birth experience. They might include communication, who supports you, comfort options or how you want decisions explained. Ask what is available at your planned birth setting and how preferences would be discussed if circumstances change. A written list is a conversation aid, not a guarantee that labor will follow a particular course. Include questions about an unexpected cesarean birth or a change in the baby's needs if those are on your mind. Your care team can explain options without requiring you to predict every possibility.

Which of my birth preferences can we plan for, and how will we discuss a change in circumstances?

A little context for these comparisons

These are approximate sizes for each week, not measurements of your baby. Babies and produce both come in different sizes, and the illustrations are not shown to scale.

Before week 20, length is measured from head to bottom. From week 20, it includes the legs, from head to heel. That change explains the jump in length between weeks 19 and 20.

When to get help

If your baby’s usual movements slow down, stop, or change, contact your maternity care team right away.

Seek medical care right away for warning signs such as a severe or persistent headache, vision changes, chest pain, trouble breathing, severe belly pain, vaginal bleeding, leaking fluid, or thoughts of harming yourself or your baby. These are examples, not a complete list. If you cannot reach your care team, seek urgent medical care. Call 911 for a medical emergency.

About this guide

Approximate measurements and development information draw on the NHS weekly guides. Linked US health resources support care and preparation topics. The topics are suggestions for discussion, not a schedule of required appointments or tests. Your own care plan may differ.

Every pregnancy is different. Your care team can help you understand your baby’s growth and any symptoms you’re experiencing.
