Is it too early!?

I had extremely light brown spotting that lasted about 1 wipe on 1/13, and again on 1/14 then on 1/17 I had brown spotting that lasted 2hours, on the 18th I had brown to light pink spotting for about 4hours off and on. I have very long cycles but if the bleeding was due to implantation would my test still be vvvvvvf 4days later?
