How your body changes in pregnancy: video

In your first few months of pregnancy, hormones flood your body. Your baby is still tiny but already your body is changing. Your breasts start to swell and may feel tender. Tiredness, nausea and frequent trips to the loo are common pregnancy symptoms.

In your second trimester, your rapidly growing womb (uterus) gradually rises up and out of your pelvis. You'll start to feel the first flutters of your baby's movements and an obvious bump will be showing by mid-pregnancy.

In the third trimester your growing baby pushes your intestines and stomach up. That's why you may be feeling breathless and heartburn is a common problem too.

Your bladder is also under pressure. You'll be making more trips to the bathroom, even more so when your baby’s head engages, ready for the birth.

These symptoms will go after your baby is born. But your womb can take up to two months to shrink back to its normal size and position.
