Cruise

Hi all I'm going on a cruise for my sisters birthday in a few weeks and will be 10 weeks at that point. I've never been on a cruise before and was wondering if it's going to be bad with the nausea. My morning sickness is very minimal but I'm wondering g if the boat is constantly rocking and if I'll get sea sick and be miserable and no fun to be around the whole week. Does anyone have any suggestions on what I could do? I've heard about these nausea bands, do they help? Any advice is helpful. Thanks!!
