6dpo or late ovulation

Allison • Mommy to Jonah 🐳🌈2/8/18 and Ezra 10/29/2020
I never track ovulation bc I can usually tell when I am glow says I'm 6dpo but today I'm have back pain and what feels like ovulation pain on one side (I have had it before) so now I'm thinking I'm ovulating late can I hurt like this with implantation? Or am I probably ovulating late I have had fertile cm for 7 days so I have no idea based on that
