It's good there's no boney injury. Keep mobile as far as you can, maybe look up knee problems on a reputable physiotherapy site on line & see if there are any physio forums online where you can get an opinion from a physio.
Last time I injured my knee, similar severity to yours, the GPs just booked me a phone call from the physio, that's in the UK. 12 days isn't long enough for a sprain or a cartilage wrench to settle down - but if it's very swollen, hot or red you need to see the GP.
