TMI but please help

Okay yesterday was one day before ovulation and I had some brown discharge on toilet paper. Today I checked it seems to have gotten worse.

I took plan B twice last week after unprotected sex (well twice) no he did not cum inside me either times. (I know irresponsible) but please any advice is this the plan b messing with my cycle .. or could it be implantation bleeding? But the thing is it’s kind of a lot and I figured implantation would be a little spotting 😥😥😥
