How can I put this delicately? There may be leaking and there may be creaking when you least expect it. Like in the middle of a silent yoga class. And you'll wish that you could just melt into your mat.
There are many reasons why you may experience leaking, but in my experience, leaking is more likely to happen toward the end of a class when your pelvic floor is fatigued or during more high-intensity exercise.
So try to start with low-intensity exercise that doesn't put too much pressure on your pelvic floor, and keep your workouts short. Just 20 minutes is all you need to get a good workout without putting too much stress on your body, and don't forget to keep working on those pelvic floor muscles.
