RAW CARROTS IN PREGNANCY

Hi i am pregnant on my second child and i am trying to eat healthy snacks etc i have been eating raw carrots throughout the day rather than always reaching for a bag of crisps but i was told the other day that it is very dangerous to eat raw carrots as Vit A is in high content in them and this is bad for you!! anyone know if this is true. I thought i was doing the right thing but now im not so sure.
