Temp drop at 12dpo

Anyone have a temp drop at 12dpo and end up with a bfp?? I know a temp drop is usually a bad sign but I’m just trying to hang on to any hope I can find 😩

I took my temp like an hr earlier than usual and it was like a 0.5 F drop. I continued sleeping and woke up again 2 hrs later and then temped again and it was a huge jump up so I’m confused. Like it was 97.90F at 7am and then 98.62F at like 8:55 am. 🤔

I usually take it at around 8am and it’s been like 98.4F on average.
