Why do i have to wait so long to find a game! Is it only me?

I made this new acc. about a month ago because I just felt like making a new acc. XD, and ever since I reached lvl 18 or so I had longer and longer wait times to get into games. at first it was 4 minutes, then it was 6 then 8 and now I wait between 8-10 minutes to find a game. can anyone tell me why I have to wait so long?

I ask other people in game how long they have to wait and most say they only have to wait at most 1 minute.
