Can Implantation bleeding occur one day before your due period?

[AmJay]

Since yesterday I am experiencing some spotting, mostly while using tissue.
My AF was supposed to start today, I am confused it is Implantation bleeding or my periods are abt to start? How soon Can I test?
Thanks

Welcome to the Forum

I would assume this is the start of AF unless....

The spotting stops suddenly then I would test after 48 hours.

Implantation bleeding quite often occurs around the time your period would be due, but unless your period doesn't start there's no way to tell whether spotting is the beginning of it or implantation. As Mamafy said if your period doesn't start you should get a clear result on a test. Good luck
