Is there still a chance

So I'm 13 dpo. I am suppose to start my period in two days. I guess I got a little to excited about seeing other women's post about getting a positive 9 dpo that i took a test. Well got a big fat negative. I was still wondering could there be a possibility I can still be pregnant or is it close enough to my period that if I was pregnant it would of showed up ppsitive. I know I probably should of waited till my miss period... guess I just been praying and hoping so long since my misscarrige so I took a test. Has this happen to anyone else. What was the results and how many dpo were you.
