Low priority queue

I don't know why, but for some reason, my low priority queue time is not seeming to go away. I had gotten a low priority queue around 3 months ago. I played around 3 bot games and stopped playing altogether. However, after playing 4 more games today, the low priority queue time is still there and that too its 20 minutes long! Can anyone tell me how many more games I have to play until the time fades?
