What is it?

My last period was October 7-11. All was normal then. Now over the last week I’ve had full cramping and 2 days ago had pain on the right side. All went away yesterday but started light bleeding like light enough to only be there when I wipe las night. Very bright red blood no clots. My period is due the 2nd week of November per this app. Per the app I am in ovulation currently. Is spotting a normal sign of ovulation or is this a possibility of being my period early??
