Implantation bleeding or period?

Ka

I am currently 6DPO. Last night before I went to bed there was a small amount of brownish pinkish spotting, this morning I had dark brown/red blood and this afternoon it turned bright red. My period is never early, it’s supposed to start October 27 so about 10 days. Hoping it’s implantation bleeding but any opinions?? Is it too early to test?
