How is this looking, honestly??

According to glow and my peak OPK I’m 9 DPO with BFN today. But according to fertility friend and BBT I’m only 7 DPO...

Can someone give me some honest input on this? Why did my temp drop today? 😟

My boobs were extremely sore yesterday but not today anymore, only an excruciating headache and I’ve cried 4 times today so a bit emotional for no reason.
