Missed period. BFN tests.

Emily
Hey glowers, 
So I am about two weeks late. I have never been this late before. Hubby and I have been trying, but when I take tests they say no. I feel like my boobs are getting bigger and they hurt a bit but they always hurt and I think I want to be pregnant so bad i could be making up the symptoms. Any words of advice? What do I need to do?
