Depending on the details of a woman's pregnancy, such as the stage it is at and whether she has any complications, mowing the lawn does not present any special dangers. Normal physical activity, if it can be performed safely, is encouraged during pregnancy, according to Patient.co.uk.
Mowing the lawn while pregnant can be treated as a normal physical activity. Unless an issue exists that complicates the pregnancy, or a doctor advises against strenuous physical exertion, moderate exercise is not generally riskier for expectant mothers than it is for other people. According to the Centers for Disease Control and Prevention, pregnant women should focus on avoiding activities that involve lying supine or entail a risk of abdominal injury.
