signs before BFP (cold or pregnant?)

Ch
Hey! I'm wondering what signs everyone had before getting their BFP!
I came home from work yesterday and was freezing even though I wrapped up in blankets and it was 72 in my house. I was freezing half of the night then incredible night sweats and woke up constantly. I've had a bad headache for a few days now, and sore throat starting this morning. AF is due in 3 days! Am I just coming down with a cold or soon to be BFP??
