26 weeks pregnant: learning your baby's rhythm
Lots of activity inside, a little clumsiness outside, and a pattern of movements worth getting to know.
Updated October 13, 2026 · sources checked October 13, 2026
In short
At 26 weeks you are near the end of the second trimester. The NHS says your baby is about 35.6cm from head to heel and their eyes are opening for the first time. The one thing to do this week: get to know your baby's usual pattern of movements, and call your maternity unit or OB-GYN straight away if it slows or changes.
Where you are at 26 weeks
Two weeks before the third trimester, which both ACOG and the NHS start at 28 weeks. In Cleveland Clinic's month grouping you are in month seven (weeks 25 to 28). Our pregnancy week calculator gives the exact week and day, and the due date calculator shows how many weeks are left.
Your baby this week
The NHS measures your baby at about 35.6cm from head to heel and compares this to a cucumber. Around now, their eyes open for the first time; blinking comes next. Eye colour is not settled at birth: the NHS explains it depends on the parents' genes, brown is very common, and it may keep changing for a few years.
Cleveland Clinic notes that your baby is making melanin, which gives colour to the skin and eyes, and that the lungs start making surfactant, the substance that helps them breathe after birth. ACOG places surfactant production and a startle response to loud sounds in the 25 to 28 week block.
Your body and common symptoms
- Clumsy and slower. Your centre of gravity has moved with your bump. The NHS suggests giving yourself more time for everyday things, like the walk to the bus stop, and being patient with yourself.
- Leg cramps at night. Pull your toes up towards your shin or rub the muscle hard. Foot and ankle exercises in the day may help prevent them.
- Forgetfulness. Often called baby brain. The NHS says it is not a medical condition; tiredness and a full head are likely reasons. Lists and phone reminders are your friends.
- Tiredness. Short rests, earlier nights and accepting offers of help count as real care.
Getting to know your baby's movements
The NHS is clear: there is no set number of movements to feel each day and you do not need to count them. Learn what is normal for your baby: when they are busy, when they are quieter. If movements slow down, stop or change pattern, call your midwife or maternity unit immediately, even in the middle of the night. Do not use a home doppler to reassure yourself; the NHS says hearing a heartbeat does not mean your baby is well.
Is this normal? When to call
Busy evenings, hiccups and cramps are normal. Call your maternity unit or OB-GYN straight away if your baby is moving less, has stopped moving, or the pattern changes; if you have bleeding or fluid leaking; regular tightenings, a dull low backache or pelvic pressure (ACOG preterm labor signs); or a severe headache, vision changes, pain below the ribs or sudden swelling. The CDC also lists trouble breathing, chest pain or a fast-beating heart, fever of 100.4°F or higher, and thoughts of harming yourself or your baby as urgent warning signs. UK: maternity unit, NHS 111 if you cannot get through, 999 in an emergency. US: 911 in an emergency.

Your checklist for week 26
For your partner
Put your hand or ear on the bump in the evening: the NHS says your baby can hear voices outside the womb, and those quiet minutes are also how you both learn the movement pattern.

Questions parents ask
How many kicks should I feel at 26 weeks?
The NHS says there is no set number and you do not need to count kicks. What matters is knowing your baby's usual pattern from day to day. Some US providers do suggest kick counts later in pregnancy (Cleveland Clinic mentions them), so follow what your own care team asks. Any slowing or change is a reason to call straight away.
Why do I get leg cramps at night in pregnancy?
The NHS describes them as muscle spasms that are common in pregnancy, often at night. Pulling your toes up towards you, rubbing the muscle and doing foot and ankle exercises during the day can help.
Is baby brain real?
The NHS says baby brain is not a medical condition and is not scientifically proven; it is something some pregnant women report, possibly linked to tiredness and having a lot on your mind.
