At 22 weeks pregnant, your baby is roughly the size of a papaya or a small spaghetti squash — about 27 to 28 cm (around 11 inches) from head to heel, and close to 430 g (about 15 oz). The headline change this week is how finished they look: eyebrows, fine head hair and defined eyelids and lips.
Week 22 is often where your pregnancy becomes obvious to other people too. Movements are stronger and more frequent, a partner may feel a kick from the outside, and your baby has moved from building body parts to refining them.
Every pregnancy is different
Every number here is an average with a wide, healthy range around it. Babies grow at different rates, symptoms arrive in different orders, and plenty of people feel almost none of this and have a completely ordinary pregnancy. General information, not medical advice — your own doctor, midwife or national antenatal programme always comes first.
How big is your baby at 22 weeks pregnant?
About the size of a papaya — the comparison most pregnancy apps and magazines reach for in the US, UK, Canada and Australia — or a small spaghetti squash if you want something sturdier to picture. In numbers, roughly 27 to 28 cm and around 430 g, which is about 11 inches and around 15 ounces.
Both are approximations. A healthy baby at 22 weeks can measure noticeably more or less and still be growing exactly as they should. What matters is your baby's own pattern of growth over time, measured by your care team against your dates — not a fruit comparison.
Why length numbers jump between charts
Up to around week 14, babies are measured crown to rump — head to bottom — because the legs are curled too tightly to measure reliably. From about week 20, they are measured crown to heel, head to toe. That switch is why one chart says 15 cm at week 19 and another says 27 cm at week 22: nothing dramatic happened, the ruler changed. Check which measurement a source uses before you compare.
22 weeks pregnant is how many months?
Pregnancy is counted in gestational weeks, from the first day of your last menstrual period (LMP), not from the day you conceived. Conception usually happens about two weeks after that, so at 22 weeks pregnant your baby has actually been developing for around 20 weeks. That two-week offset is why your own maths and your app's dates sometimes disagree.
In months, week 22 sits at the end of the fifth month, with the sixth about to begin — most people simply say "five months". You are in the second trimester with roughly 18 weeks to go. If you want to see how this week fits into the whole picture, our pregnancy week-by-week guide runs from the first positive test through to your due date.
What your baby is doing this week
At 22 weeks your baby looks like a miniature newborn — thin, red and wrinkled, but recognisably a baby rather than a foetus on a chart.
- A face with features. Eyebrows and fine hair are visible on the head, and the eyelids and lips are now well defined.
- Eyes formed, colour undecided. The eyes are fully formed, but the iris still has no pigment. Eye colour keeps developing before birth and often changes for months afterwards.
- A developing grip. Your baby grasps whatever is nearby — the umbilical cord, their own face, a foot — which is how those reflexes get practised.
- Hearing that recognises you. Your voice, heartbeat and digestion are the soundtrack in there, and your baby is starting to know your voice specifically. A loud noise can prompt a visible startle.
- Rest and activity cycles. Your baby sleeps and wakes in stretches that rarely line up with yours — which is why the kicks arrive the moment you lie down.
What you may be feeling at 22 weeks
The second trimester is usually kinder than the first, but week 22 brings its own list. Common around now:
- Stronger, more definite movements. Less like bubbles, more like nudges and rolls. A partner may feel them with a hand on your bump, though it is hit and miss at this stage — an anterior placenta, or bad timing, hides them completely.
- Braxton Hicks tightenings. Practice contractions can start around now: your bump goes hard for 30 seconds or so, then softens. They are typically painless, irregular, unpredictable, and they usually ease if you change position, empty your bladder or drink some water.
- Stretch marks and itchy skin. Pink, red, purple or brown lines across the bump, breasts, hips or thighs, often with mild itching as the skin stretches. They fade to silvery lines; nothing reliably prevents them.
- A navel that has popped out. Harmless, very common, and it usually settles back after birth.
- Nosebleeds and tender, bleeding gums. Extra blood volume and hormonal changes make the membranes in your nose and mouth fragile. A soft toothbrush helps; tell your dentist you are pregnant.
- Nowhere comfortable to sleep. Side-lying, with a pillow between your knees and one under the bump, is what most maternity teams suggest as pregnancy progresses. If you wake on your back, just roll over — no harm done.
One note on movement: you should not be formally counting kicks at 22 weeks. Structured counting comes much later, once a clear pattern exists. But once you are regularly feeling your baby, any reduction or change from what is normal for you is worth an immediate call — at any hour, however many times you have called before.
What to do this week
Nothing here is urgent, but it all gets harder to arrange later.
- Book antenatal or childbirth classes. Popular ones fill months ahead and are usually timed for the late second or early third trimester. Hospital, community and private options all exist.
- Start thinking about a birth plan — without committing. Notice your preferences on pain relief, positions and who you want with you. A birth plan is a set of preferences, not a promise, and changing it later is completely normal.
- Check your appointment schedule. In several countries a routine mid-pregnancy appointment or anomaly scan falls around now. Schedules genuinely differ between countries and clinics, so follow your own doctor, midwife and national programme rather than any timeline you read online, including this one.
- Ask before you take anything. Medicines, vitamins, supplements and herbal remedies all need clearing with your doctor, midwife or pharmacist first, however gentle or routine they seem.
- Start the leave paperwork. Checking your entitlements is easier at 22 weeks than at 32.

Most of what you feel this week is ordinary. These are not, and none of them are ever a bother or an overreaction:
- Vaginal bleeding, of any amount.
- Severe or persistent abdominal pain, or tightenings that become regular, rhythmic or painful. Braxton Hicks are irregular and settle; contractions that keep a pattern at 22 weeks need checking straight away.
- Fluid leaking from the vagina, whether a trickle or a gush.
- Fever, or feeling unwell with chills.
- A severe headache with visual changes such as flashing lights or blurring, or sudden swelling of the face, hands or feet.
- Pain or burning when you urinate, or needing to go much more often than usual.
- Intense itching, especially on the palms and soles or worse at night — this needs a blood test, not a cream.
- Reduced or changed movements, once you are regularly feeling your baby.
- Any sudden, severe symptom that frightens you, including painful swelling or redness in one leg.
Whether this pregnancy feels straightforward, or you are carrying worry from a previous loss, or you are doing this on your own, week 22 is a good moment to be kind to yourself. No one can promise how a pregnancy will unfold — but you are always allowed to ask, to ask again, and to call your care team whenever you need to.
