High mercury fish

My husband and I order our meat and seafood from a company. We started ordering black cod, which is also known as sable fish. We did not realize this is a high mercury fish until today. I’ve eaten it a few times this pregnancy and now feel horrible!!! And have accidentally eaten tuna in sushi. My husband orders it and tries to get one without but one had it. I’m freaking out!! Will baby be ok?? I’ve always been great about avoiding it and have now eaten high mercury fish a handful of times. I’m 27 weeks and worried!!
