You can have about 12 ounces of seafood a week, just watch fish. Some is higher in mercury and other toxins than others. But from what I have read, shrimp is low in toxins and good to eat :)
I ate them all trough my 1st trimester and my baby girl is fine so I'd say yes :)
I am kinda being lazy but then again I just got done eating lol
Yes you can eat shrimp. Make sure its cooked tho. I eat it almost on daily basis.
