BBT & OPK?

It says I “peaked” yesterday according to the strips but it says on another app I’m 5dpo. I don’t believe that. I do believe I am maybe at my peak and should BD 24-36 hrs? thoughts?

I was using “premom” tab for a bit until realized I should be using “others” I use the Natalist. I am so confused cause it says CD9 “peak” but the other tab says I peaked yesterday at CD14. the opk from yesterday is way darker.

If I peaked on 25th CD 9 I would be 4dpo. Dunno if that’s correct, maybe someone can help me?
