Has anyone else ever experienced or heard of this??

Okay so I’m 9dpo and I’ve been just keepin an eye on the implantation bleeding. Nothing yet... but I did find this is my CM it’s uterine lining or something. It doesn’t look or feel like paper 🧻 or anything. It is tissue that came out. I did have light cramps... is it possible (if anyone knows) that this is from implantation?? No spotting what so ever. Just lots of CM... I have never experienced this before?? Has anyone else?
