Can I Still Be Pregnant?

Hi, I've been trying to conceive since early June 2017. I missed my period this month by 13 days but when af showed it was lighter than usual, didn't smell like period blood (sorry tmi) and it ended abruptly after 3 days. it did not tamper off it just stopped completely. I've taken multiple hpt all bfn. I'm curious if there's still a chance??
