Implantation Bleeding @ 11DPO?

Kyara

Today is CD 30 and I’m 11DPO (have had 4 bfns to date). I normally ovulate late in my cycle. My cycles are normally 29-32 days Today my cm changed to a slight brown color. After my bf and i had sex i went to pee and i saw a noticeable amount of white and brown discharge. I went to the gym and came back to super light brown spotting. Hours later it has subsided.

My breasts have been tender for 2 days now, which is a symptom I’ve never had for AF and the only cramping I’ve had was a mild lower back pain.

Has anyone else had brown implantation bleeding/spotting/Cm around the same time AF is due? Did you get a bfp right after?
