Your baby

The arms and legs are lengthening, and the head is beginning to uncurl. The upper and lower parts of the body do not grow at exactly the same pace, so your baby's proportions look very different from a newborn's. The raspberry comparison gives a rough sense of size while these early structures continue taking shape inside the uterus.

Your body

Nausea and frequent bathroom trips may interrupt your routine. You might also feel excited one moment and worried the next, or feel differently from people around you. Physical discomfort and poor sleep can make emotions harder to manage. You do not have to wait until feelings become overwhelming to bring them up with your prenatal care team.

This week

Caring for your emotional health

Think about who feels safe and supportive to talk with. At your visit, describe how you have been sleeping, whether worries are hard to control and whether you still enjoy your usual activities. Ask what counseling or mental-health support is available if you need it. If you already receive mental-health treatment, discuss a pregnancy care plan with your clinicians rather than changing medication yourself. Seek immediate help for thoughts of harming yourself or someone else; those concerns should not wait for your next appointment.

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.
