I have never experienced this with any of my pregnancies..so don't know much. Which of course led me to obsessive googling. It says that it normally happens 6 to 12 dpo. Well..I od sun and last night (so 3dpo), I wiped and had a tiny amount of slimy brownish red discharge. It was only the 1 time, and of course I'm obsessively checking. I have never had spotting mid cycle either, so really hoping it was implantation bleeding, but don't want to get my hopes up. Any thoughts or similar stories?
