I’m 11 dpo and bleeding. It seems like a lot when I wipe, and it’s red, but there is barely anything on my panty liner. I took a pregnancy test and it was negative, but it also wasn’t first thing in the morning because I couldn’t pee enough. Yesterday I had some blood just in the morning, but didn’t even end up wearing a panty liner all day. I slept in one though because it seemed to start again when I was getting ready for bed.

Is this likely my period arriving or implantation bleeding? Is there even any way to know?
