Not surprised

I knew I was going to get a BFN today but I decided to take a test anyway because it's the last one I have and I was sick of looking at it every time I opened my drawer. My next period is due 11/24/14. I used the clear blue digital since it's supposed to be so good. But another BFN. Not surprised. Not really even trying anymore. I just won't be buying anymore any time soon ?
