You're fine... Shellfish is fine during pregnancy just make sure its cooked well and steer clear of large high mercury fish. I was the same way and the only "meat" I ate my entire first trimester was seafood.
if you eat baked clams make sure they are throughly cooked! Im not sure you should be eating 10 at a time tho..lol. My ob told me no more fish then 3 times a week or so. im going to put a link but idk if you will be able to see it. This article is very helpful!
You want to be careful. They main reason is because it is so was to get food poisoning from seafood plus some gas mercury, some have parasites, ect. So just be careful and you should be fine...and limit it.
