Implantation bleeding how long did it last for you ladies? At what week of weeks did it occur?

I didn’t have any.

I had it for one day it was brown, blood no clots nothing. It happened when my period was like a week late. I didn’t even need to wear a tampon but I assumed that was the beginning of my period.

I didn’t see mine

Some people don't see any of either, at all.

Depends. There are two different types of implantation bleeding. You have implantation of the fertilized egg which occurs a little before, or about the same time as your period would have shown, and you have placental implantation, when your placenta attached to the uterine wall. I had implantation bleeding with my daughter that was the same length , time, and consistency , as my regular cycle. Didn't end up finding out I was pregnant with her until my cycle was missed the second month of pregnancy, and I threw up. Never had implantation bleeding with my other two pregnancies. The only time I had placental implantation during pregnancy is with the baby that I am pregnant with now it started at 6 weeks and ended a little after 11 weeks.
