Week 28

To facilitate rapid foetal growth, the uterus expands significantly during pregnancy.^1,2 During the third trimester, up to 17% of women and birthing people may experience sciatica due to the growing uterus and additional weight gained throughout pregnancy.² 

Symptoms can be made worse by prolonged sitting, standing, sneezing or coughing, and can affect quality of life.²

Fortunately, sciatica can be eased with self-care, including heating pads, warm baths, stretches, and rest.¹

If you are experiencing discomfort related to sciatica that isn’t easing with self-care, speak with your healthcare provider for further support.¹

Entering the third trimester, the lungs and the supporting network of blood supply (pulmonary capillaries) have matured, allowing for better gas exchange. Additionally, your baby has now accumulated enough fat so they can regulate and maintain their own body temperature.⁴

These physical developments of your baby are important, because if it were to be born prematurely at this stage, it would have a good chance of surviving.⁴
