Spotting or period?

Rain

Hey all, if I have light bleeding for three days but not enough to fill a pad or tampon but enough to wear a liner and occurs when I wipe, would I go ahead and probably consider this my period? I am 9 days late at this point and just have this spotting going on. I am generally very regular and normally start off with one light day and then three heavy days so this is very unusual. No stress changes or changes in meds or anything that I would think could cause me to be so late. Thoughts?

Edit: I took a test at about 5 days late and it was negative but women in my family have a history of not having high levels until further into the pregnancy
