Confused? Implantation spotting or early?

Cla`aron

So my period is suppose to start tomorrow, however I had this today and I typically do not spot prior to periods! If I were to start early it would be darker so that’s why I’m confused , I did do a PH suppository last night so I was okay with feeling liquid sensation but not the light pink color .... typically when I do a boric acid suppository it is white white white when it cleanses so idk I guess I’ll find out tomorrow ? Also it seemed to only be pinkish once the third pick is 2 hours after the first two pics
