Anyone get a faint positive on 6-7dpo and been ok?

Got a faint positive tonight. Off of opks I'm 6dpo. If I ovulated around the time I got a positive opk I could be 7dpo but I doubt any earlier. I know I am at risk to ectopic because of scar tissue on my Fallopian tubes so I'm worried. It's possible the tests wrong, but if not, is that even possible or is that a bad sign getting an early positive?
