Aunt flow? Implantation?

Feeling confused. I've have implantation bleeding with two pregnancies. No question, bfp two days after. I'm currently 10dpo and this is coming from my cervix when I check. I spotted once today, but otherwise its just on my CM. My cervix is pretty low so I can't tell if this is AF on the way, or implantation bleeding.

I stopped birth control over a cycle ago, so im also questooning if my luteal phase is shorter.

The pic looks similar to the other pregnancies too but I had it earlier than 10dpo. Im also cramping on and off sinxe 6dpo.

Does this look like anyone else when you are about to get your period?
