What to avoid during the TWW

So my husband and I are TTC and I’m currently 6DPO and the wait to test is KILLING me but I’m trying not to focus on it too much. With that said - I know to avoid drinking and obviously don’t smoke (I don’t, just making a point), BUT my sweet gem of a husband planned a big ol date night at this local oyster bar for the two of us and I know oysters are a big ol no no during the pregnancy but was wondering if it’s okay for me to eat Oysters during this time??

This may be a dumb question.. I’m just wondering what the do’s and don’ts are of this whole “am I pregnant”/“am I not” waiting game!
