Your baby

Fingers and toes are separating, and tiny nails are forming. The body is growing while the head remains relatively large. Your baby moves inside the uterus, but those early movements are usually too small for you to feel. Not feeling movement now is different from a change in an established movement pattern later in pregnancy.

Your body

You may still feel tired, nauseated or warmer than usual. The way you feel does not reliably predict what an ultrasound will show. It is understandable to have mixed feelings before an appointment, especially if you have experienced a previous loss or difficult pregnancy. Let the team know if there is something that would help you feel more comfortable during the visit.

Preparing for an ultrasound conversation

If an ultrasound is planned, ask what question it is intended to answer: dating the pregnancy, checking development or contributing to a screening assessment. Ask whether any preparation is needed and when someone will explain the results. Scan timing and what can be seen vary with the situation, and not every pregnancy follows the same imaging schedule. Write down unfamiliar terms so you can ask about them afterward. If follow-up is suggested, ask what remains uncertain and how the next assessment may help clarify it.

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

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.
