TMI sorry everyone

Three days ago when using the bathroom I noticed the smallest bit of pink discharge. It was just dot on the toilet paper. I didn’t think anything of it and went about my day. Well, this morning I woke up and my panties were bluish green from discharge. Nothing on the toilet paper. Not an STD. No smell. Just stained my white panties with this color. So strange. Just now I went to the restroom and there was a small amount of brown spotting on my underwear. This time I took a pic. I know that’s gross. I usually spot the morning before I start my period. But I’m still four days away.

Could this be implantation?? I know the only way to know for sure is to test, which I will after I hold my pee in for a bit but does anyone have similar stories that ended in a BFP???
