Implantation or start of AF??

Update: trying not to get my hopes up. But I’ve had no more spotting since I posted. My temps are still elevated too.

Has anyone had implantation bleeding? I’m day 10 dpo and have super light barely there spotting. My cervix is closed. Normally I spot around 13 dpo and my cervix is open when I spot. Trying not to get my hopes up but is this possibly implantation?
