I really don't mean to scare u but please think twice about this trip!! This wasn't related to a cruise but I did experience GI when I was in the 2nd trimester of my pregnancy. Up till then, no problems. It was a horror to get severe abdominal pains, and the "runs", and not be able to take anything. I thought some of those pains were early labor pains. I thought I was losing my baby! I had already lost 2 prev. pregnancies. The Dr. had me on bed rest for the next couple of days! Now imagine that when you're many thousands miles away from home! Would u be comfortable going to a possibly underdeveloped area hospital? and that's if u could even get to one!!!
