No period for three months now!?

My period hasn't come, after about nine months of a regular light spotting period every month it just stopped. I have been getting cramps, backaches headaches, sometimes I feel nauseous but it goes away eventually. Since I've stopped working all I do is sleep I don't know why. I know I should just take a test already but I'm just scared of what the results will be. Been ttc for a year straight and have had no luck whatsoever. Just wish I could get some baby dust over here..
