Raw oysters during pregnancy?

Hi mummies :< this might seem like a very small problem to my friends, family and even husband, maybe to some of you too.. but i have been craving raw oysters every single day for the past 2-3 months. i am currently 21 weeks and i have been crying/breaking down several times the past few days whenever i get hungry because the temptation to eat it is just so strong, might be hormones messing me up too but i have been very depressed honestly. are there any substitutes i can replace it with? similar texture/taste? ive never been a fan of cooked oysters, i would throw up whenever i eat them, even before pregnancy too. so i was wonder if there are substitutes or other foods i can replace raw oysters with.. please help mummies, i know its a small issue to just endure for another 5 months, but i am desperate
