Swordfish, tilefish, king mackerel, and shark contain high levels of methylmercury. This metal can be harmful to your baby. You can safely eat up to 12 ounces of seafood a week, so choose fish that are low in mercury: catfish, salmon, cod, and canned light tuna. If you like albacore (white) tuna, limit yourself to 6 ounces per week. Check with your doctor before taking fish oil or any other supplements while pregnant.
