Your baby

Your baby is curled inside the uterus with legs bent toward the body. You should still notice movement as your baby shifts, even though space is becoming tighter. The cantaloupe illustration is a rough size comparison. Neither the shape of your bump nor the place you feel a kick reliably establishes the baby's position on its own.

Your body

If your baby moves lower into the pelvis, you may notice a change in pressure or more bathroom trips. That does not happen at the same time for everyone and is not a reliable way to predict the start of labor. If pressure comes with contractions, leaking fluid or other concerning symptoms, contact your team rather than assuming it is simply the baby settling lower.

Asking about your baby's position

Ask when and how your clinician will assess your baby's position. If the baby is not head-down later in pregnancy, the team can discuss what that means for your situation and which options may be appropriate. Do not try exercises or maneuvers advertised to turn a baby without first discussing them with your clinician. This is also a good time to confirm the planned birth setting and whom to contact if symptoms develop before your next visit. Any change in the usual movement pattern needs prompt advice regardless of position.

A question for your next visit

When will we check my baby's position, and what options would we discuss if it affects the birth plan?

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.
