Pregnancy symptom

I know we all symptom spot and can drive us crazy! I'm just wondering if anyone has gotten a cold in early pregnancy as a sign even before any missed period. If so, what dpo?
  I'm thinking it's the crazy weather Change where I live, but I NEVER get sick, so this is just something completely new to me! I mean really, never, I'm a teacher and even around all my little germ boxes my immune system is incredible.
