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 a frequent need to pee are common pregnancy symptoms.
In your second trimester, your growing uterus gradually rises up out of your pelvis. You will start to feel the first flutters of your baby's movements and be showing an obvious bump by mid-pregnancy.
In the third trimester, your growing baby pushes your intestines and stomach up against your diaphragm and lungs. That's why you might be feeling breathless, and heartburn is a common problem too.
Your bladder is also under pressure. You'll be making even more trips to the bathroom as your baby drops lower into your pelvis, usually at about two to four weeks before delivery.
These symptoms will ease after your baby is born. But your uterus can take a month or so to shrink back to its normal size and position.
