Is having “a cold” an early symptom of pregnancy?

Sarah

So I am currently 9-10dpo and i am feeling absolutely awful. i took off from work today, which i never do because i am a teacher. I have felt so sick, tired, and having really bad headaches. i have been ttc since march with hubby but haven’t been successful. i haven’t taken a pregnancy test yet because i am terrified to see a negative and get that sad feeling. Just wondering if anyone has felt ill (like had a cold) before they actually knew they were pregnant?
