Af came late?

Lindsey • Christian, Married, Mommy of 2 boys, step mommy of a little girl :) TTC our rainbow baby :)
So TTC for over a year af is like clockwork but this month it came two days late and it's a medium flow (well light to me) no clots or anything...it started this morning and is already almost gone...? Is it possible to have ovulated late causing a late implantation ?? Or am I just in denial again?
