Secondary bbt dip post O

[DobbyForever]

Hey! I'm bored so going to post a poll. I have been charting consecutively for 4 cycles and 6 total. I always get a singular dip at 5 or 6 dpo, which I assume to be my secondary estrogen dip. Today (7dpo) I got a half degree dip. I have slow falls into AF that start as early as 9/10 dpo. My lp for all but my last cycle were 12. Last cycle was 14. Obviously, my next few temps and an hpt will take the mystery out but just curious who else has gone through this and what resulted.
