Is getting sick a good sign?

Flor
Ive heard that getting cold/flu symptoms is a good  early pregnancy symptom. My older sister got the cold in her three pregnancies, my younger sister did too in her three pregnancies. Actually, i knew she was pregnant before she even thought she could be just because of the "cold" she got a few days before her missed period. Im due 02/09, and im sick. I have the cold which started with a slight headache and sore throat around yesterdays evening, and i woke up so much worse today. I posted earlier about taking meds for it, but ive decided to just go with the flow as much as i can without meds and ill see what three more days brings me. Has anyone detected their BFP by the cold and then a missed period? Im almost excited about this, but its hard to stay hopeful, when your body is sick :/ im hoping for my positive test soon :) 
P.S. i dont mind hearing a little bit about anyones story, so comment below if you'd like :) God Bless 💜
