I think my body is just truly broken

I have been TTC for five and a half years I have endometriosis and have had several chemical pregnancies over the years. My cycle tends to run early rather than later. And in the small handful of times it has gone over it has it has only ever been a day or two. I'm five days late. I tested both Friday and Saturday. Both were negative. I'm feeling a bit defeated and like my body truly is broken. I can't even bare the though of hoping I'm pregnant just to it dashed for the hundredth time.
