Need comfort!

Since yesterday I've gone to the Drs 3 times and hospital once. Ive been dealing with symptoms that mimic pregnancy. The only problem is I got two BFN at the Drs. I may or may not be pregnant but I am only 8dpo. Isn't that a little too early to tell? I don't want to rule that out since they still have no idea whats going on with me. Also how sensitive are the urine tests at the Drs?
