Huny you'll be #1 whe they weigh crab legs theyre weighing evening includingthe shell not just the meat so you really prly ate ab 10oz. Last time I had crab legs I ate 3/4 of a lb lol I love cran legs my fav. And they are a safe seafood to eat during pregnancy. Only thing you really stear clear of is albacore tuna,swordfish,shark,tile fish, mackerel, Basically all your deep sea big high mercury fish. And yes about 12 oz a week is what were supossed to eat. But your fine hun no worries.
