11 days? You are doing all right.
At that stage I recognised the problem, but still went out doing minor shopping errands for the sake of my sanity. I always carried a stack of spare pads in my rucksac and got to know exactly where every public toilet was, and which shops had them.
Life began to settle down noticeably around 6 weeks, but I needed to be prepared for a pad change until about 6 months.
Walking can still be an issue 7 years later (though salvage RT might have set me back a bit). Problems mostly come though if I go for a walk in the evening, or after some physical activity (e.g. gardening) which obviously tires my sphincter. Recently though I walked the Tour du Mont Blanc (for us 144 km and 8450 m vertical ascent over 10 days) and never needed to change pad more than once in a day.
You will learn what works. Cycling seems less problematic than walking for me. The thing that catches me out are activities where you need to brace yourself by using the core muscles which increase the pressure on the bladder (and thus work the sphincter hard): pruning in the garden, or some painting DIY in the house. I never think I have done that much excercise but find myself leaking more in the early evening. But overall at the worst I only need 2 pads a day, and I keep a spare in my back pocket always.
Good luck, and be patient.
