Temp spike at 13dpo

Leah • Leah

So yesterday and today I have a tiny bit of brown spotting. I tested yesterday and got a BFN. I assumed AF was coming, but this morning my temp spiked. I don't have any symptoms other than an increased temp and light brown spotting.

I thought temps were supposed to decrease before AF. That's how it was last month... so what would cause temps to spike at 13dpo?

I'm not complaining at all! Just curious.

TIA
