I would stay away from these until you speak with your doc..I know that many types of fish are not safe when you are pregnant..I would certainly ask your doc and see if he/she has some sort of list as to what foods to avoid during pregnancy..Some docs have these and it may help you so that you don;t have to worry about everything that you eat being safe for your baby.

It might pay to avoid it in case of listeria or heavy metal poisoning (unless you can check the source of the fish). 

its really only the HIGH risk food poisioning stuff that you need to worry about. if you buy tinned ones they should be ok. but freash from the sea is the best.

fish is ok to eat while your pregas so long as its cooked well like it should be even if your not pregas just to be safe, but yeah it should be fine just eep an eye on your self after eating fish if you feel ill just go to hosp and inform them you ate fish and are pregas.

Yeah Sardines are ok.  Packed full of Omega 3.

People shouldn't eat certain fish while pregnant but I feel sardines which are full of calcium are fine.

I haven't seen it on any no no foods list, so should be safe.  They are actually very high in calcium, so go for it!  Just don't do what one lady I knew did.  she smothered hers in chocolate fudge sauce!!!!!!
