Implantation?

Stephanie
Okay, my period was Jan 13th til the 18th. But I wasn't bleeding anymore on the last day of my period so we have sex (unprotected) well on Jan 29th I had some brown/red mucus discharge. Not enough to fill a panty liner. Happen the 29th and a little in the morning the 30th. Could that have been implantation? Could it have happened that early?
