COD liver oil

Hi ladies - I have recently been seeing a nutritionist who has put me on COD liver oil as it’s good for women trying to conceive. When I told my family (they don’t know I’m TTC) they said they’re glad I’m not pregnant as it’s bad for the baby. Just wanted to know if anyone here has been on cod liver oil? I’ve heard mixed reviews and can’t wait till next Thursday for my next appointment because I’m so damn impatient! Thanks 😊
