What on earth is going on? FF is having a nightmare

An

I’ve had a dip in temp today from 36.74C average luteal to 36.36C. According to FF advanced setting I’m 16dpo (but I doubt it as my average luteal length is 12). FAM setting puts me at 10dpo today. With the temp dip, FF is now saying I haven’t ovulated on the FAM setting and isn’t sure on advanced setting. I have also gotten what I think could be the start of a bfp 🤷🏻‍♀️

What are your thoughts here?
