My wisdom teeth ain't too wise

I went to my ortho on friday to get my next set of trays I'm now on tray 14/20 for the top so nearly there 3/4 through...yay! So I mentioned to my ortho that my wisdom teeth seem to be coming through well atleast the back bottom right hand side one has decided to show itself. Excuse my ignorance but I was thinking considering I have closen gaps that I would have ample room for my wisdom teeth to come through perfectly....NOT the case she told me that it looks like I will have to have them removed because there doesn't seem to be enough room and if I don't get them removed I will end up with crowding issues grrrr 10 steps forward 1,000 steps backwards so she informed me that we would get some xrays done in May exactly 1 year from the time I got my first xrays I'm really hoping that My mouth finds the room for these not so wise teeth or They will atleast hold off from ruining my whole course of Invisalign until I can get them removed. AND that I will either get more hours at work or a nice pile of money will land on my lap! Because I am not looking forward to having to spend more money on my teeth as far as I know it can cost a couple of thousand dollars to get your wisdom teeth removed plus a couple of weeks off work. I can't afford that I have to pay of my Invisalign, pay off my car and save $10,000 for a course I want/need to do!!! Life isn't it grand sometimes....
