Spotting or implantation bleeding

Angelica

Hey everybody! Kind of new to this app.

I have a question. So my periods are really regular they come maybe 1 day before or after, or same day. So I notice when something isn't right. On Saturday I started spotting quite a bit, then Sunday was still spotting but not as much and today I'm not spotting at all and I'm suppose to start my period tomorrow. I'm so confused 🤷‍♀️. Could it be implantation bleeding or is my period just acting weird.
