af due today nothing

I usually have cramps for at least 2-3 days before period and nothing went to go potty wiped and very light pink like barley there and erg white cm I usually have glue like cm right before period and when it comes it's never light its full on heavy sorry tmi could this be implantation? Or break through bleeding also bbt is still high and I know for a fact I've already ovulated so that's not it
