Big bbt drop at 6dpo, possible implantation dip?

Megan
I've been reading that around 7dpo you can experience a big drop a major drop, which they consider an "implantation dip". I'm praying I will see my bfp this month. They said the dip should only last one day and the next day it will shoot back up. So I'm usually around 97.4 and it dropped to 96.2 and today its up to 97.2. I'm 7dpo. Anyone else experience this
