Unexpected bleeding

Danielle

My period is not supposed to start until the 17th which I know is close but so far away. Anyway I wiped and had some blood today not a lot but enough to know what it is. I got off my birth control in July, we have not been doing ovulation test just having fun with everything. I’ve had a fairly normal period since coming off bc. My period comes every month on the 17th so I am confused. Could this be implantation bleeding?
