Your womb will begin to get bigger more quickly and you'll really begin to look pregnant.
You at 22 weeks
Not everybody gets stretch marks, but if you do, they will probably start becoming noticeable when you're around 22 to 24 weeks pregnant.
They may appear on your stomach, breasts and thighs. At first they can be pink, red, purple or brown, depending on your skin colour. They may gradually fade into paler scars and become less noticeable.
Your breasts may start to leak a little pre-milk – this is normal.
You may also notice skin changes in pregnancy. Find out more about skin changes on our page about common health problems in pregnancy.
Your baby at 23 weeks
Your baby's lungs are not yet able to work properly, but they are practising breathing movements to prepare for life outside the womb.
Your baby gets all their oxygen from you via the placenta and will do so until they're born.
You at 23 weeks
You may develop piles (haemorrhoids). Piles are swellings containing enlarged blood vessels inside or around your bottom (the rectum and anus).
Piles can happen to anyone, pregnant or not, and can be very uncomfortable. They can happen when you're pregnant because hormones make your veins relax, but there are ways to ease piles in pregnancy.
Tiredness and lack of sleep are common in pregnancy. There are plenty of things you can do to help yourself sleep, including using pillows to support your growing bump.
Your baby at 24 weeks
By the time you're 24 weeks pregnant, the baby has a chance of survival if they are born. Most babies born before this time cannot live because their lungs and other vital organs are not developed enough.
The care that can now be given in baby (neonatal) units means more and more babies born early do survive. But for babies born around this time, there are increased risks of disability.
You at 24 weeks
You may get thrush in pregnancy. Having thrush when you're pregnant can be irritating but it will not harm your baby. Your midwife can recommend treatment.
See your doctor or midwife if you have any pain when you pee. This could be sign of a urinary tract infection (UTI) that needs treating.
You can find more information on pregnancy in the 'Your Pregnancy and Birth book'.
