Bleeding during the Pregnancy is not a good sign...especially bleeding like Period, I dont want to be terrible person but you might be having miscarriage, dont wait for your Doctor go to the Hospital right away. I hope everything will turn out alright.
Only thing comes to my Mind is that you put it in your Head that you are Pregnant and you are just refusing to believe otherwise...
you got Periods and you Got negative tests what more proof do you want? I am sorry but your time will come its not just Yet...
She would only go 1 month Over if her dates were wrong and Instead of 40 weeks she was like 36 or something because NO Doctor would let her go Over week 41
