Heard that doing lots of jumping and jogging makes women incontinent. Is that true or is leaking just noticeable?

Likely exertion. Jogging is a considerable amount of exercise. It might put strain on muscles, your heart, and your lungs. Your bladder is another organ that can react to stress. Exertion is a stressful event and depending on your age/health situation, you may be taking drugs for and have other conditions that can affect bladder function. Unless this is interfering with life activities, it is probably normal.
