Backache is one of the most typical mild pregnancy symptoms. It typically manifests as a dull discomfort and stiffness in the mid and lower back, making it difficult to get up from a sitting or sleeping position. It is likely to worsen as the pregnancy advances. The majority of such backaches do not indicate a serious condition. However, the rapid development of back discomfort, especially if accompanied by other symptoms such as vaginal bleeding, may be a warning of an approaching miscarriage. Back pain at the end of pregnancy may signal the start of labor.
