Fish Cravings

Since I've been pregnant I feel like I've wanted fish quite often. I can probably count 8 times I've had it maybe a few more. I've read that too much can cause issues. The types that I have eaten are lobster, fried clams and Scollops (one time I power puked it back up 😖) Cod and Haddock and white tuna in like a Mac salad. I know none of these things are considered to be on the "high Mercury" list besides the Tuna, but like I said I didn't have it in a huge amount, but I just wanted to check and see if anyone else has eaten fish this many times and what your experience is. I'm am literally paranoid about every single thing. I don't want to do anything to hurt this baby and I'm a first time mom. When I panic I turn to google which doesn't always give you the answers that you want 🙄
