5 days past period, all negative tests


Was due to start my period the 11th of this month, I’m nearly 6 days over feeling all symptoms I felt with my son and all negative tests. Got my implant removed 28th September and dtd and ovulated that weekend and dtd both days, is it even possible to get pregnant this soon after implant removal 🤷🏼‍♀️🤔 How many days past period should I get a positive x
