i am worried because i ate crab legs and shrimp probably 3 times before i knew i was pregant and on occasion i have shrimp and today i ate chunk light tuna fish, i read in some meagaines that shrimp and tuna are safe and others say is not, i just got off the phone with my doc and he said its ok but dont eat a lot of it, the nurse i talked to said she ate seafood all the time when she was pregnant…..any advice, im worried about my baby
