Help any hope left?????

Nicole • ✨TTC #1 since 10/1/18✨👼🏻

My chart has been crazy today is my 2nd significant dip today is 11dpo for me and 2 days before af is expected. Do you think I’m out or could it be a later implantation or definitely feel ugly af is making her presence known??? I was trying to hold on to hope but these bbt make that hard.
