I was 14 weeks pregnant with twins when we cruised to Bermuda. Prior to the cruise, I had terrible nausea and vomiting. Once I got on the ship, I was fine, never felt a thing. In fact, one night we hit rough seas and everyone in my party felt sick except for me. I got to eat all the food everyone couldn't (LOL)! Like floridaminnie says, everyone is different. Good Luck!
