22 weeks pregnant - what to expect

Your baby now weighs one whole pound! From around now, they start to weigh more than the placenta. They’re about the size of a papaya.

What does my baby look like?

Over the next few weeks, your baby’s taste buds will continue to develop and they’ll be busy practising swallowing in readiness for life outside your womb.

What you eat now could affect the flavours your baby prefers after they’re born, so eat plenty of healthy food.

Your baby’s lungs are not yet ready for life outside the womb but they’re developing fast. Even though they can’t breathe in the womb, your baby’s practising breathing movements for life outside.

They get all their oxygen from your blood via the placenta until they take their first breath after they're born.

Smoking decreases the amount of oxygen in the placenta, so it’s very important to stop if you’re still smoking.

Your symptoms - what to expect

Spotted a stretch mark?

Stretch marks are pink or purple marks that appear on your bump, or possibly boobs and thighs. They eventually fade to silver.

Hormonal changes during pregnancy make your skin more prone to stretch marks as your bump grows. Creams that claim to prevent or stop them are unlikely to have any effect, because they can’t penetrate deep enough to where the damage is.

However, it won’t hurt to very gently massage your bump with nice oils or creams if you find it relaxing, and might make you feel better about your new ‘badges of honour’.

Keep an eye out for swollen feet and hands

If rings on your fingers feel a bit tight or your shoes a bit snug, this is probably due to the increased fluids in your body, known as oedema.

However, get medical advice from your midwife, doctor or the hospital straight away if you have the following signs:

  • Sudden severe swelling
  • Swelling on your face as well as your hands and feet
  • Bad pain under your ribs
  • You are vomiting
  • You have a severe headache or problems with your vision.

These symptoms can be signs of pre-eclampsia.

Actions to take

Is it safe to diet during pregnancy?

Pregnancy is not the right time for a weight-loss diet. It is a time to eat well for both you and your baby. If you try to lose weight, you and your baby may miss out on nutrients that you need to stay healthy and strong.

If you’re concerned about weight gain, remember that if your diet is healthy, much of what you put on will be lost with the birth of your baby and the placenta.

What is BMI and why does it matter?

Don't forget your pelvic floor!

Make sure you give your pelvic floor muscles a workout as part of your daily routine. Toning up your pelvic floor muscles will help you ease your baby out and recover more quickly after the birth.

They will also help stop you weeing by accident, especially when your growing baby starts to press on your bladder.

“I exercised throughout both my pregnancies, right up until my due date. I was a lot more tired in the second pregnancy, because I was running around after my daughter, but I always did something active because it made me feel better.”

Aileen, mum of two
