I'm 11dpo and af is 2 days late. I haven't really had any symptoms other than back ache. But today I started getting a brownish discharge when I wipe (sorry this is gross and tmi!) It's like more watery than creamy cm and is not cloudy. It's there when I wipe but gone when I rewipe if you get my drift. I keep reading about implantation spotting, but everyone seems to describe it as being red/pink. I don't have any of my usual af symptoms, and she has never ever ever been late. I got a bfn when I poas earlier today. Any advice?
