Tuna is very high in mercury. I craved tuna during my first trimester and it took all of my will power to not bing on it. You can have 2 small servings of tuna a day and that's the max. You can have your tuna wrap today, just no more than 2 in a week. If you buy tuna at the grocery store, the white or albacore tuna is higher in mercury than the light tuna. So, don't even buy the white or albacore. Also, buy the tiny cans. You can have half a small can 2 times a week (that means no more than 1 small can for the whole week). The large can is more mercury than you should have for an entire week, so don't even buy it. Shrimp, pollock, salmon, and catfish are low in mercury and you can have up to 12 oz a week unless you've also eatten tuna during the same week.
The Mayo Clinic advises pregnant women to have no more than 2 servings of fish a week. For llight tuna it should be no more than 6 oz a week.
