anyone../?

Is implantation bleeding literally a little speck of pink on toilet paper...?  I wiped there was a tiny tiny pink dot on it I'm kinda freaked out I just ovulated like 2 days ago I haven't had sex but I've been paranoid about pregnancy my BF was rubbing me through my leggings but his precum may have soaked through his pants onto his hands through my pants l.. is that even possible or am I over thinking it?
