Implantation bleeding and positive test 11dpo?

Hannah

This morning I woke up with what I believe could be similar to implantation bleeding and cramps. My period isn't due for another 4 days. Is it possible to have implantation bleeding and receive multiple vfls? I tested on 4 different brands and all gave vfls. This was also not with fmu. I have been testing since 6dp and these are the first lines I have ever seen.
