implantation? need help ladies

Shelby

hi ladies!! i just need some opinions. the first day of my last period was 9/19. on 10/8 i had spotting that lasted all day and was mixed with discharge, only when i wiped, then disappeared. exactly a week later on 10/15 i randomly got an AF feeling cramp but ONLY in my lower left abdomen which lasted maybe 5 seconds then disappeared. my next af is apparently due on 10/24. is it possible that was ovulation bleeding and then implantation?
