Implantation bleeding?

Anyone had any experience with implantation bleeding? I'm currently on cd26 of a 32 day cycle so I'm a week away from my regular cycle. I'm cramping, have headaches, nausea and I spotted brown today but nothing now?

I typically just cramp and get sore breasts approaching my period?

Wondering could that have been implantation? 🤷‍♀️
