Since you were very early in your pregnancy, and it's possible for the dates to be a little off, I would say your baby is probably just fine.

I also had a ct scan done and also had the die injection done, however, I was 11 weeks pregnant.

According to the hospital and my doctors, the amount of radiation that is actually given off is very little with todays equipment.

Its not like the old days.

Hope that helps ease your mind a little.
