Week 22 sits within the second trimester. The senses and facial features continue maturing while the fetus gains strength. This guide explains what may be happening now, what can vary, and which concerns deserve prompt professional advice.
What is happening at pregnancy week 22
Skin, ligaments and pelvic structures adapt to the growing uterus. Gestational age is counted from the first day of the last menstrual period, so early numbered weeks include time before conception. Dating may later be adjusted using clinical information and ultrasound.
Baby development
Eyes are formed though iris colour is not established, and touch responses and hearing continue developing.
Approximate size and growth
The fetus is approximately papaya sized, around 28 centimetres head to heel.
Changes you may notice
Stretch marks may appear and the navel may flatten or protrude. Some people notice several changes at once, while others feel little different. The presence or absence of a symptom cannot on its own confirm how a pregnancy is progressing.
Common symptoms
- Skin stretching
- Pelvic or back discomfort
- Braxton Hicks-like tightening may occur for some
These experiences are possibilities, not a checklist. Symptoms can be mild, strong, intermittent or absent at week 22, and a different pattern does not automatically mean that anything is wrong.
Emotional wellbeing
Visible changes can draw comments from others. You can set boundaries around body discussion and medical questions. A short daily check-in can help: notice what feels manageable, identify one source of support, and write down a concern instead of carrying it alone.
If worry is persistent, interferes with sleep or daily life, or makes it hard to cope, tell your midwife, doctor or another trusted healthcare professional. Emotional health deserves the same attention as physical health.
Nutrition and hydration
Continue balanced meals and discuss cravings for non-food substances promptly, as these can be linked with deficiencies. Sip fluids regularly and use urine colour and thirst as everyday prompts, while following any fluid advice given for a medical condition.
Aim for regular meals built around vegetables and fruit, wholegrain or other fibre-rich foods, protein foods and suitable dairy or alternatives. Follow local advice on prenatal supplements and foods to avoid; individual needs differ, especially with allergies, diabetes, anaemia or severe nausea.
Safe movement and daily comfort
Pelvic-health physiotherapy can help when pain affects walking, sleep or daily tasks. Choose an intensity at which you can still speak comfortably, include rest, and adapt for heat, balance changes or pelvic discomfort.
For an uncomplicated pregnancy, comfortable everyday activity is often encouraged. Stop and seek advice if movement causes pain, bleeding, dizziness, chest symptoms, fluid loss or contractions. A clinician can tailor advice for complications or a previously inactive routine.
Appointments and screening
Care may include fundal growth assessment, blood pressure and discussion of upcoming glucose testing where indicated.
Exact schedules and tests vary by country, pregnancy history and care plan. Keep a note of new symptoms, medicines and questions so your appointment can focus on what matters to you.
Warning signs and when to seek care
Trust a strong sense that something is wrong: maternity services would rather assess a concern than have you delay because it does not match a list.
- Contact your maternity service promptly for vaginal bleeding, suspected fluid loss, severe or persistent abdominal pain, a severe headache, vision changes, sudden swelling, fever, breathing difficulty, chest pain or feeling acutely unwell.
- Once you have established a usual pattern of movement, seek maternity advice promptly if your baby is moving less than usual or the pattern changes. Do not wait for the next day.
- Use emergency services for collapse, severe breathing difficulty, heavy bleeding, a seizure or another immediately life-threatening concern.
Practical preparation for this week
Think about infant feeding education without pressuring yourself to make every decision now.
- Set boundaries around unwanted advice
- Seek help for activity-limiting pain
- Ask when glucose screening is offered
Frequently asked questions
Are stretch marks preventable?
They are influenced by skin and growth factors; moisturiser may ease itching but no product can guarantee prevention.
What are Braxton Hicks tightenings?
They are usually irregular and settle with rest or hydration. Painful, regular or increasing contractions require maternity advice.
Should I compare my pregnancy with someone else at week 22?
No two pregnancies follow an identical pattern. Dating can vary, symptoms are influenced by many factors, and growth is assessed over time rather than from a single comparison. Bring personal concerns to your maternity team.
Week 22 in brief
Week 22 combines sensory maturation with visible body changes. Protect comfort, boundaries and access to pelvic-health support.
