Help with my bbt chart

[Nataliexx]

Does my chart look fine?
I had a massive temp drop this morning (I'm O)
Never had a huge temp drop like that though.
Is it normal?

Wow, that's a big drop! You might have had two eggs releasing at the same time! I don't think I've ever seen a drop that big!! I hope you got to BD on the same day as that big dip! (If not, you should still be covered from the BD on CD 12.) Good luck!
