Prime rib ok??

Alysha
Help! I am going on a much needed date night tomorrow night with my husband and we are going on a dinner cruise and the main entree is prime rib... I I know we have to avoid undercooked meat but are prime rib and steak ok? I know hamburger isn't ok when not cooked thoroughly. I desperately need this date night and don't want to be worried sick about hurting baby....
