Implantation dip?

Tamara

Hi ladies,

Not sure what’s going on with my temps, today’s dropped way below the cover line? 7DPO and no symptoms (obviously) other than INSANE VIVID dreams, which I never get. Just worried this big of a dip could mean af is coming?

I’ve also seen a bunch on people on here say the implantation dip is a myth? Any thoughts?
