Chart help!

Anna
So yesterday morning I had a huge dip and I immediately thought I was out. I had cramps all day yesterday so I definitely thought AF was on here way. Yesterday I was 10 dpo. This morning, there's no sign of AF, cramps are gone, and my temp went way higher than my coverline again. I tested this morning and got bfn. I know only time will tell, but any insight would be appreciated!
