Help!!

Hey y’all. I am need of some advice, AF is due in three days however I have been having a “cold”, sore boobs which never happens, clear gummy like cervical mucus for the past couple of days with some minor (the slightest) cramps. I know these things can all happen before af but I never have the CM or sore boobs so I’m hoping that we are pregnant! I took a pregnancy test yesterday and it was negative 😫. What do you all think? Have y’all ever went through anything like this?
