Implantation?

For those of you who had implantation bleeding, can you explain the symptoms you had at at the time? I got my “period” tuesday morning. it was really light and by thursday it was gone. it was never heavy or clotty like it usually is. Thursday and friday I had really achy hips and lower back and yesterday and today slight migraines. I didn’t have implantation bleeding with my first so I wouldn’t know what to compare it too. Also waves of nausea since yesterday
