How can you tell if it's implantation dip or af is coming Temperature at coverline at dpo 9 but period isn't due for another 2-3 days?

Answer:
If it is an implantation dip, your BBT should rise again after. Most women don't have an implantation dip. If it remains low, it is likely that AF is coming. It is normal to see a decrease in BBT 2-3 days before AF, and actually happens for most women.
