Implantation of af?

Chloe

Hi everyone! I’m 3 days late, this morning I had a Cm with a tiny tinge of pink in it, then nothing until this! After this I wiped and wiped and wiped and there was nothing! But I’m wondering if this is too much blood to be IB? although it’s a lot darker than AF blood.. I also alwayssss know the instant I start AF as I get a certain pain, but haven’t had that pain either. Thanks in advance.

Edit - I’ve taken 3 morning pee test on each missed day, including today and they’re bfn
